In the building where I do performance analysis, there is a curtain error.

Hello. I have a project to finish tomorrow. There are interesting beam and column dimensions, but ignore it, I applied the same as in the previous project. When I do performance analysis, I get immediate usage in one direction and pre-failure and crash errors in other directions. When I looked at the details, I saw that a single curtain failed on several floors. The building was finished and usable. We had to save. I contacted the building control, they say save it somehow:) (the owner of the building control already drew the project at the time) they say you can make small changes, we will ignore the beams. Since the project is big, I uploaded it to the site, if you can take a look at the attachment, it would be greatly appreciated. thanks...

Re: There is an error in a curtain in the building where I do performance analysis Hello My suggestions; There are errors in column, beam, foundation, slab data entries in this project. Your concrete value is C25. You haven't done DS (rebar fixing) anywhere because of the decrease in reinforcement. If these reinforcements are in place, there is no need to strengthen them. After correcting the incorrect data entries and making calculations, the building can be used. (Even as it is, it saves.) There is no need for PERFORMANCE analysis. But if there is a decrease in dimensions, reinforcements and concrete values, after detecting the situation, entering these values into the program and making DS, Performance calculation you should.

Re: There is an error in a curtain in the building where I do performance analysis Dear Gencideci, I understand from your article that the building has not been done yet. If this is the case, performance analysis is unnecessary and inaccurate. Performance analysis, load, material coefficients, R coefficient, etc. Many other evaluation criteria are considered for existing structures and their logic is completely different. It gives an idea, but using it for one-to-one control can lead to such inconsistencies. In the 2018 regulation, some types of structures require performance analysis, but the performance analysis in the 2018 regulation is also very different from 2007. If your building is an existing one, the horizontal reinforcement is weak in the aforementioned shears. This is the reason for the brittleness. Ø8/16 horizontal reinforcement is actually weak. Requires reinforcement. It is necessary not to use reinforcements lower than 10 gauge (my preference is 2 gauge) on the wall horizontals.
 
Re: In the building where I made a performance analysis, there was an error in a curtain It was said by the building inspection that the building was an old building performance analysis was needed. must ensure safety. and 39% column damage is seen in the damage, it should be reduced to 30%
 
Re: There is an error in a curtain in the building where I do performance analysis Dear youngcideci, Strengthening and performance analysis are subjects that require experience. First of all, as Unver said, you should correct the data entry errors. It would be wrong to say that much was understood from the file you sent. Did you take a core sample? Are these enough? Have you done the reinforcement reads and strips? Are these the values you entered into the project? More importantly, is the carrier system really the way you entered it? Or is the manufacturing different? I feel like there are reinforced walls and columns in your design, but data entry is not like that. (For example Plus, I think you don't have enough knowledge of the regulation. Your interpretation of the regulation is different. (What are you basing the sentence of the 30% collapse zone on? See life safety performance level criteria of the attached regulation) Especially "building it is finished and usable. We need to recover it.I contacted build control, it says recover somehow (already build control owner drew the project at the time ) you can make small changes, they say we ignore the beams. " sentences are incomprehensible. Moreover, it is the building control that says this. What are we saving from whom? Performance analysis requires a good examination. Frankly, it is not a computer head job. Suat Bey As he said, there are many factors. It is important not who drew the project, but how it was implemented. For example, what is the condition of stirrups? Corrosion situation, etc. etc. So first of all, I advise you to hurry up in a hurry to train and do someone's work. I don't. You should definitely get support from an experienced person. You should read the existing structure very well on the spot. You should not go for evaluation over the project. Best regards.. N.

The building is an old building performance analysis was said by the building inspection. It needs to provide life safety. and 39% column in damages it seems damaged, it needs to be reduced to 30%, my respected elders, if you help me, I would be very happy if you would make a correction and upload it here, take it easy for all of you... There is a field available, but only engineers with sufficient experience can do this. First of all, necessary data must be collected for performance analysis. These are survey construction information, material and ground information. I assume you have a project, but it is not sufficient. On-site control is required. Again, you can get reinforcement information from the project, but on-site Confirmation by stripping and x-ray is required. Concrete should be cored. For quantities, you should refer to section 7 of the 2007 regulation. Your building is a frame type structure considering the curtain ratio. So ductile behavior is a structure that should be expected. In this case, wrapping and column-beam connections become more important. You need to make sure these are done in place. Corrosion condition, ground condition, it is not enough to have these in the Project. There is no such thing as the regulation allows 30% damage. As seen in the article sent by NYILMAZ, there is a 20% shear rate limit for the advanced damage level of the columns. There is a limit of 30% for beams as well. But there is no permission to migrate in any way. Assume that you have obtained all the data and analyzed. You need experience to interpret. Unfortunately, it is not possible to learn this experience through e-mails. I suggest you seek professional support.

Re: There is an error in a curtain in the building I'm doing performance analysis There is a problem of shear force in my project, I read the comments in the forum, although I played around with both the cross section and the horizontal and body reinforcements, I could not solve the problem. I would be very grateful if you could help. I want to add the project, but I can't because of the file size.
 
Re: There is an error in a curtain in the building where I do performance analysis I sent it to your gmail, unver, can you check?
