Analysis Settings

[teknikisler]

One of our senior engineers says that when performing static analysis, we should select the option "Apply the horizontal loads calculated by the mode combination method to the rigid diaphragm", and other options will produce incorrect results. As a reason for this, it says "If you are analyzing according to TDY 1997 AND 2007, check this option" in the description for the mode combining method in the Help document. I usually analyze with "semi-rigid diaphragm" and "use response spectrum solution with eccentric moment loading on the diaphragm". Which of these analysis methods we use, we can reach more realistic results.

Hello, Your choices are correct and "take into account earthquake effects in flooring design" must be marked[/i ] "concentrate the floor masses at the diaphragm center" option must remain NULL (no sign) With this analysis method achieve the most realistic results. z. Good work

Mr. Hakan, I apply these analysis methods in all projects regardless of A2 A3 irregularity. However, my sections are more comfortable than fully rigid ones, this creates a disturbance in me, is this normal? 2) While modeling the system, I save my sections relative to semi-rigid. When I analyze the last time with the full rigid diaphragm option for comparison purposes, I see sections that do not save. Since we analyze semi-rigid analysis (with response spectrum method) with slabs, shouldn't these concrete sections also save in full rigid analysis? good work
