Thanks for clear explanation.

Hi,

When I checked my pushover curve, I noticed that initial elastic part of curve changes before the structure reaches first yielding occurence during analysis. Is it because of numerical iterations or something else? I'm curious because when I search typical pushover curves from different ...

Hi Tim,
Actually my main reason to do that I need participation factor which uses mode shapes normalized by top floor so this value should be something between 1 and 2. So I just wanted to verify values that I used to calculate for this factor. (Also second post of this topic from fbianchi suggested ...

Hi,
I want to ask 2 quick questions:
1)To calculate effective modal mass for X direction of 3D structure in excel I followed the steps below:
-I took nodal displacements of corresponding period and also modal masses in X direction. Then used in excel with the equation to calculate effective modal ...

dear rui,
thank you for your answer.

Hi,
I have 2D model that I need to connect two frames(external and internal frame from 3D) at each floor level with pinned pinned connection using elastic element. I created elfrm with high axial and flexural stiffness and when I tried to put moment release(M2a and M2b) for ends it didn't work(for ...
