HELLO, I had a few questions 1-) I just started using version 7 of idecadin. In previous versions, there was no option such as semi-rigid diaphragm and full-rigid diaphragm, although I did research on this in the analysis settings, I am not satisfied. I couldn't find anything convincing in my project when the analysis is done in semi-rigid diaphragm, there is no alpha i error if I make a fully rigid diaphragm, alphai error occurs, I got the r coefficient, I would be glad if you could help me on this matter 2-) when I have a dynamic analysis in the same project, it does not give any error, but in the risky building analysis, the curtains on the ground floor 3-) when I make beams between two curtains, the shear forces are constantly excessive. How can I prevent this 4-) How can I fix the shear safety control of the column-beam junction area without disturbing the architecture (without any misalignment), thank you in advance for your interest. You can download the project from the link below, good work [url =http://www.4shared.com/rar/KaisFvNnba/hkn_sonn.htm l]http://www.4shared.com/rar/KaisFvNnba/hkn_sonn.html[/url]
