The problem in linear performance analysis is spring beam. Currently, Spring beams are taken into account in normal analysis but not in performance analysis. You can create it by drawing arc and converting to beam. In the updated version, arc beams will also be considered in linear performance analysis.

Hello. Therefore, if you analyze your 5 version project in 6 versions, it may give a torsional control error."dester":7czcmnis" said:thank you for your attention. It's not urgent. I just wondered what the cause of the error was. Also, in the previous version, the saving beams give a torsion error in this version, I wonder what the reason could be. I'm waiting for your reply

The first page of the Linear Performance analysis report contains information on Earthquake direction and Status.In Building 4 earthquake loading, Immediate Use, Life Safety or The result of the analysis takes place as the collapse zone.The most unfavorable situation is taken into account in the evaluation of the building result.So if there is a life safety in the +X -X +Y earthquake direction, but there is a collapse in the -Y earthquake direction, it means that the building is in the collapse zone."SCETCHER":xuubo8vy" said:shall we evaluate the usage status of the building according to the percentages on the last page of the report?
The level of knowledge is considered medium according to the average value of the information we have obtained. However, I still chose limited in terms of security. because there is no project, but we can count the column reinforcement sprouts and the dimensions of all beams, and the reinforcements of some beams. On the other hand, hand-cast concrete core tests under the conditions in 92 were average with values between 13-14. 13.2 is out. column sizes are 80/25 and above - there are some vertical beams with beam sizes 60-70-80/32. the dimensions are adequate but the concrete quality seems quite low. that is, if the concrete is good, the building will almost not require reinforcement. but some beams require reinforcement. that, how will the reinforcement in the ridges be? Are we going to add another beam next to the beam:? We can add columns to some large openings. but how can reinforcement be made in the vertical beam?
The level of knowledge of the building is clearly defined in TDY 2007. Even if there is no project, it is decided at what level it should be taken according to the regulation by looking at the data such as the detail of the relief and how many elements have been stripped. Core values are not directly averaged, but a value is found by taking into account the standard deviation as given in the relevant Turkish standard, and this value is considerably lower than the mathematical average. Considering that the values you give will decrease with the standard deviation, it would be wrong to think that a structure of this concrete quality would not require reinforcement. Whether a structure requires reinforcement and how it will be strengthened depends entirely on the behavior and performance of the structure. Please do not try to strengthen without doing enough research and learning and gaining experience. As in the examples I will give in the training I will present at İzmir IMO on November 22-23, strengthening requires very different problems from normal building design and detailed solutions specific to the situation of each building. Otherwise, it can lead to very dangerous consequences. For the purpose of the beam reinforcement (such as increasing the moment capacity, increasing the shear capacity, transferring the load to the newly added elements, etc.), a reinforcement should be made. For this reason, there is no answer to the question that the beam is strengthened as follows.
I think I asked the admin where the analysis result, which was written in a different place (at the end of the report) in the new version 7.01 than the 5.51 version, would appear, considering whether it was left to the user's view according to the percentage values. but you exaggerated and talked about education. It's been 9 years since my education period ended, Mr. Suat. You can find the reinforcements in columns and beams with the film device without stripping. It makes no sense to shave a column of minimum 3 - 6 cm in a structure with low concrete quality. The things you call open are so absurd that a new one is added every day to the missing articles you call that regulation. They wonder what regulation they will issue to rob and defraud the nation, like the registration number nonsense about the latest contractor decisions. In addition, Relayve will only help you with architectural elements. You can never find out clearly where a beam passes and how many reinforcements it has, with processes such as surveying and stripping. How do you know that a construction worker didn't cut someone with a beam iron for the sake of a tickle while pouring concrete? Not everything is solved with theory. tomorrow to the master on how to strengthen the beam; At this point, I think you will increase the moment, you will increase the shear capacity at this point, you will increase the performance of the building in this way. You can join my training tomorrow. If you are going to teach, do some research on this topic. The beam reinforcements pass each other as much as the interlocking length in both directions, but why is the reinforcement of the column, which is the main carrier, clamped in one direction to the column in the lower and upper floors? addition of the concrete and reinforcement in your logic, which I showed with the red line in the figure, at the base point where torsion, which is the weakest point of the column, is. The reinforcement drawing I have shown with the blue line is my logic and the joint point is to prevent torsion by adding at the point where the shear force is maximum. I do not understand which engineering logic accepted this event, but you do not hesitate to express that you know a lot and will give training. however, you need more education. Think of a table and apply a force to the leg of the table by hammering 10 Q6 nails into a wooden floor on which you put your foot on the table, and you will notice that the foot is displaced. however, on the wooden floor where this foot will sit, create a slot half the length of the nail and apply force again. You will measure the level of knowledge of me and you. LOAD. INS. TECHNICIAN SINAN BASAN"suatyy":2kl5ta74" said:The level of knowledge of the building is clearly defined in TDY 2007.

I'm sorry to hear you take my words, Mr. Sinan, I wanted to warn you at this point as I have seen erroneous comments such as averaging the concrete core values directly. Of course, there are faults and deficiencies in the regulations (by the regulation I mean the Turkish Earthquake Regulation, I am not talking about other implementing regulations). The regulation I mentioned was made for the first time in 1974 in Turkey and changed in 1998. Then it was revised in 2006 (this was not a very comprehensive change, 7 chapters were added about retrofitting). Lastly, it was revised in 2007, that is, it has been revised 3 times in our 88-year Turkish History, so as you mentioned, it does not change every day. Regulations always give minimums to avoid mistakes. As long as you prove the accuracy with your calculation methods, you can go beyond the regulations. There are dozens of examples on this subject, if you wish, you may not even use the earthquake acceleration spectrum. You can also use the earthquake data specific to your region or the data of another earthquake. Engineering is the science of putting theory into practice. However, this does not necessitate deletion of regulations. They are usually minimums and only guide and prevent you from crossing red lines that would cause error. Contrary to the devices you mentioned, they do not give clear information, they have a sensitivity of +- 2 mm. Stripping gives more precise information. Since you cannot strip all the elements, the regulation gives a statistical approach to this issue. Regarding the column joint you mentioned, the regulation already imposes a penalty if the joint is made where the moment at the base is maximum (torsion, as you would say!) and increases lb by 1.5. If you do this in the right place where the tomorrow moment is minimum (it is done in serious buildings), you will not be penalized. Frankly, I am glad that you have completed your education, because I have been continuing my education, including master's degree, for 22 years, but I think I am still at the beginning. Admitting what you know means closing the door to knowledge. I can estimate your level of knowledge from the questions you ask, but I cannot comment on this. In addition, when I come across someone who knows a subject that I do not know, I listen and try to learn without being offended. It can be a master, sometimes a worker, a technician or an engineer, it doesn't matter. I recommend it to you too. A saying is 'The less a man knows, the more he thinks he knows, the more he knows, the less he realizes that he knows.'
has also taken into account our analyzes and evaluations regarding reinforcement, and it is foreseen that 8 column reinforcements and 4 columns sheathing will be applied to the building in the beams that are found to be weak, and he has 40 years of experience in strengthening the beams in this way. , we have decided together with the respected high engineer of our region and tomorrow we will go from theory to practice. In other words, when a graduate engineer is needed here, he trains us not only to produce theory in the program, but to show actions by exchanging ideas with people you think are uneducated, by giving us information on the points he deems lacking, with his experience. I have helped our respected architect-engineer brothers in the construction of around 400-500 projects so far by using the program in their calculations and drawings, as well as personally applying them at the construction site, and I continue to be still. I have not had any problematic projects in the past years, except that my 3-4 projects were objected to by the contractor on the grounds of excess reinforcement (such as the fact that rote contractors, obsessed with 27 kg per m2 for a 5-6-storey building with a 2000 head model, did not accept the average reinforcement of 35-40 kg per m2). didn't happen. We grew up with the pride of working with an engineer who didn't hesitate to throw away the project of the contractor who says too much equipment. we do not hesitate to go the way he went. The idea that it is wrong for people who can claim that the wall carries the beam, to be a site manager by limiting the powers of the technicians in a country where it is decided to be an engineer with a piece of paper, is from the mentality that argues that an architect-civil-electrical-mechanical engineer who has just graduated from school and has no experience can be a site manager. what can you expect? An engineering mentality that attaches importance to paper for years, does not hesitate to find fault with the technicians with the severe shaking of earthquakes. These are the bullshit you call regulations. since this is your opinion, remove the technical department and it's over. If necessary, I will go Pasha Pasha and do it in labor with a diploma. they don't care about diploma in that profession, they care about the right of the wrist. though a construction worker can earn more income than a technician or engineer."SCETCHER":1c50y79s" said:I think I asked the admin where the analysis result, which was written in a different place (at the end of the report) in the new version 7.01 than the 5.51 version, would appear, considering whether it was left to the user's view according to the percentage values. but you exaggerated and talked about education.

Lastly, it was revised in 2007, that is, it has been revised 3 times in our 88-year Turkish History, so as you mentioned, it does not change every day. Look at the articles that were amended in 2011, a new decision was taken almost every day and a new regulation was added. not only on earthquake regulations, but also on the construction industry. Also, I don't claim to know much. Frankly, it upsets me that your approach to the subject is a little different and that you crossed the boundaries of criticism to different dimensions while trying to explain that what he claimed about the subject we were discussing here with a young engineer was wrong. I'm sorry, I always respect your profession. It is also a good thing that you have taken your education this far, but what I meant by education was school education. Human beings learn something new from every job they do, you are right about that. but we're just left with learning. Before we have a chance to implement it, either the law changes or we change.
Then it was revised in 2006 (this was not a very comprehensive change, 7 chapters were added about retrofitting). I would also like to offer your opinion. In 2006, the strengthening regulation comes out. however, it is foreseen that such buildings should be demolished in 2011 and that the demolition will be carried out by the state itself. ie a license period of 5 years. Even a building built in 2005 may have to be demolished. A hotel in Van, which was renovated under the name of retrofitting, turns into a grave with a 5.6 earthquake. Moreover, my own opinion is that you may think differently, I respect, even looking at the building with the eyes of a citizen with no engineering knowledge, one can observe how weak and bad it is with the rotten appearance of the building and the ugliness it gives to the architecture. however, such buildings hide their ugliness with paint-polish and coating method. I can't make any sense of the fact that the 100-year-old building, which is almost in the middle of the road, mostly on the main street in the center of the bazaar, is protected under the name of historical artifact. I mean, as a passer-by outside of my technical personality, I pass by the building every day with the fear that it will fly over me. However, the state neither demolishes nor restores such structures. in other words, it is officially an invitation to disaster. It is really important to keep the history and the future alive, by demolishing such buildings without causing any harm to the environment and by making them from scratch in a more suitable place without occupying the streets and pavements, in a way that will not harm the environment. in other words, it will be more economical to re-do it rather than trying to strengthen it.
What you are talking about are the implementing regulations, which are generally issued with daily political and economic concerns, Mr. Sinan, I am not talking about these, I agree with you in most of them. But let's not confuse professions. There are 75000 civil engineers in this country, they are registered to the chamber and all of them are authorized to sign and are authorized for everything. THIS IS WRONG. My diploma says 'Has been awarded to be a civil engineer'. This means that he is entitled to become a civil engineer. That is, he does not say that he has become a civil engineer (that is how I understand it). In college you are given a dough and it is up to you to shape it. If you train yourself, this is a minimum of 5 years for a civil engineer, and 10 years for me. It is wrong to give authorization once you get the diploma. This is not so in the world. It takes a minimum of 5 years for a civil engineer to get authorization. Sometimes it doesn't get any. All professions collide when the signature and the project get cheaper. Technicians try to make projects. Instead of learning how to do projects, engineers are in a hurry to earn money by worrying about making a living. So what is the truth? The project is done by a civil engineer, but under the supervision of a competent engineer (a competent engineer does not mean an engineer with one or more years of experience. He is an expert engineer who has passed serious exams in his profession and has proven himself with what he has done). Construction Technicians also make the drawings of the project for which the engineers calculate (engineers do not draw) and implement it. What I mean by doing a project here is calculation, not drawing. Empowerment is a specialty in itself. (By the way, it is just decoration, not retrofitting in Bayram hotel). Unfortunately, since the specialties in engineering are not separated, everyone is trying to do it now, and this is why the wrong practices you mentioned arise. So what should the above figure be? 10.000 competent engineers 65.000 civil engineers 250,000 Technicians There is no construction without technicians. In practice, it is the job of the Technician. Without my technician in my office, a project would not come out of my office. Of course, I am explaining the model that should be here and that is in the world. So how is the situation in our country? In the middle, we saw it once again in Van.
suat bey, our thoughts are exactly the same. The project signature authority should belong to the engineers. OK, I agree with him. However, I think that a civil engineer who does not know how to calculate, does not know how to read a project, does not know how to make a project, should not be given that authority, even if he has authority. In order to find a job in the newly graduated market, a situation arises such as doing a job with an invoice amount of 100 TL for 40 TL. In this case, he will not be able to earn money even if he does the project. however, he avoids taxes because he works for the amount of tax he will pay to the state. Every authorized person and all architects-engineers know this. A newly graduated technical person should not have the authority to do business alone without having the experience of an architect-engineer-technician. As you said, the authorization restriction, which is only for engineers for 2 years, should be applied to all technical people for 5 years. meanwhile, he should have experience working under a competent engineer under the name of assistant. You also think that the application is the work of technicians. however, the authority of the technicians to lead the construction site is abolished. If it is considered in terms of employment, every construction should have a technician under the supervision of the project owner, so that the complete authority is not removed, but a construction without a technician is not carried out. however, these technicians should meet the same conditions as engineers and be given competence as you said. I have no doubt that all architects-engineers and technicians realize what you are aware of. I mean, there is no need to compare a newly graduated architect-engineer with a technician with 10-15 years of experience. You know better which one is more experienced. There are no sanctions in our country. all the confusion stems from this. A law, not a regulation, should be enacted, and whoever neglects his job should be able to regain his authority within the time limit by taking his authority in parts and showing goodwill. I recently shared my thoughts on the building control regulation on this subject in the form."suatyy":4c77dykm" said:What you are talking about are the implementing regulations, which are generally issued with daily political and economic concerns, Sinan Bey, I do not talk about these, I agree with you in most of them.

THIS IS WRONG. On my diploma it says 'Has been awarded to be a civil engineer'. It means he has been qualified to be a civil engineer. So he doesn't say he became a civil engineer (that's how I understand it). In college, you are given a dough to shape it. It depends on you. If you train yourself, this is a minimum of 5 years for a civil engineer, and 10 years in my opinion. It is wrong to be authorized once you get the diploma. This is not the case in the world. It takes a minimum of 5 years for a civil engineer to get an authorization. Sometimes he can't take it at all. When the signature and the project get cheaper All professions collide with each other. Technicians try to make projects. Engineers do projects. Instead of learning how to make a living, they are in a hurry to make money. So what is the truth?

won't be a bother, and if you have the time you'll find our thoughts are similar. Also, I really misunderstood what you wrote last night. I realize now that it was nothing to exaggerate. I guess I misunderstood because of nervous stress, with the program giving many errors and my work wasted. I am so sorry. When I first read it, I made a sense as if they were insulting the technicians, so my stress, which was on the line, increased. I just read it again and I'm really sorry.
