Calculation of A2 and A3 Irregularities and what to do in the program

[engineer_yildiz]

Questions about A2 and A3 irregularity are on the pictures. I will be glad if you answer. 1- We made A2 and A3 calculations, the program gave a warning "The concrete compressive strength is not enough, bending reinforcement needs to be placed" Why does it give this warning and what should we do in this case? 2- What do the terms in the report mean? 3- What kind of analysis and formulation does the program use in the calculation? 4-We found A2 and A3. Do we need to mark or what should we do for many diaphragms on the floor where there is irregularity in the Floor Parameters dialog? What does our marking contribute to? What happens if it is unchecked? I wish you good work.

Dear idecad officials, the questions about A2 and A3 irregularities are on the pictures. I would appreciate if you could answer. 1- A2 and A3 calculation We had it done, the program gave a warning "The concrete compressive strength is not enough, bending reinforcement is required" Why does it give this warning and what should we do in this case?

This warning is given when the Moment/Strength moment formed in the investigated slab section is less than the tensile strength of the concrete The amount of As given as a result of the calculation can be placed above and below the section shown in the picture

2-What do the terms in the report mean?

The meanings of the notations used in the report are as follows.

3- What kind of analysis and formulation does the program use in the calculation?

The formulations are also given in the picture above.

4-We found that A2 and A3 are Kat Do we need to mark or what do we need to do for many diaphragms on the floor where there is irregularity in the parameters dialog? What does our marking contribute to? What happens if it is unchecked?

Re: Calculation of A2 and A3 Irregularities and what to do in the program Dear Sir, The subject in the link you referenced: It was for the case of solving any floor as a single diaphragm, My question here: In case of more than 1 diaphragm in the same floor, in the Floor Parameters dialog how should I mark it (we determined that it is -A2 and A3. Do we need to mark for many diaphragms on the floor where there is irregularity in the Floor Parameters dialog or what should we do? What does it contribute to if we mark it? What happens if it is not ticked?) what should I do? ? We kindly request you to take the example in this title as a reference and evaluate it. Maybe you are explaining enough, but I may not be able to notice because I am missing something. Thank you for your patience and help.

Re: Calculation of A2 and A3 Irregularities and what can be done in the program Solve them with a semi-rigid diaphragm without dealing with them at all. In the tiling calculation, the program already takes these effects into account automatically. In other words, your floors are equipped to take the tensile and compressive forces caused by the earthquake in the flooring.

Solve them with a semi-rigid diaphragm without any hassle.The program already takes these effects into account in the slab calculation. In other words, your floors are equipped in such a way that they can absorb the tensile and compressive forces caused by earthquakes.

Dear Sir/Madam, I would appreciate if you could clarify the subject by supporting abstract concepts with concrete examples without skipping the related questions. (There is no A2 irregularity in the rest of the system.) This example is most common when the stair flats have a transparent roof. Or when the lower floors (basement + ground + 1st floor) are workplaces. 2-If your answer is yes, A2 irregularity whether or not Reinforced concrete systems Solving Semi-Rigid means getting more accurate results than Rigid acceptance 3- Applying TS500 criteria Isn't it to ensure that the structural system elements that make up the good form a Rigid System? Or are there points that I missed or didn't see? If applying TS 500 means making the construction rigid, do I not have to solve the construction rigid (even if there are irregularities that cause it to be semi-rigid on some floors)? I feel like I'm in a spiral as the questions increase.

Do not bother with these and solve them with a semi-rigid diaphragm. In the tiling calculation, the program already takes these effects into account automatically. In other words, your floors are equipped in such a way that they can take the tensile and compressive forces caused by the earthquake in the flooring.

Dear Sir/Madam, I would appreciate it if you could clarify the subject by supporting abstract concepts with concrete examples without skipping the related questions. There is no A2 disorder in the rest of the system, only). This example is most common when the staircase flats have a transparent roof. Or the lower floors (basement + ground floor + 1st floor) appear when it is a workplace. 2-If your answer is yes, does solving Reinforced Concrete systems with or without A2 irregularity mean getting more accurate results than Rigid acceptance? 3- Isn't applying the TS500 criteria to ensure that the structural system elements that make up the structure form a Rigid System? Or are there points that I missed or didn't see? If applying TS 500 means making the construction rigid, do I not have to solve the construction rigid (even if there are irregularities that cause it to be semi-rigid on some floors)? As the questions increase, I feel like I'm in a spiral.

1) In any case, solve the semi-rigid diaphragm in the system with or without A2. 2) Yes 3) First you need to understand the concept of semi-rigid. If we didn't call this method "semi-rigid" for short, but gave it a long name to describe the job it did, we would say " I SOLUTION BY INCLUDE FLOORING INTO THE CALCULATION". In the rigid diaphragm, the calculation is made by disabling the building floors. Roughly like this. Visualize a reinforced concrete carcass structure. But cut out the floors of this structure and share the load of the floor with the beams around the floor. Then replace the tiles you cut out with an infinitely rigid diaphragm. Let this imaginary diaphragm you put move that solid as a whole, let it bend and twist, let it not break or crack. Rigid diaphragm is something like that. "Rigid Diaphragm" is an admission. And it's an approximate solution. It is rational to use this method when you have a more accurate, more sensitive and advanced method. However, for this method, your computer must be both fast and have sufficient memory.
