Hi,
I'm doing a MPA 3D but I have some problems.
I'm studying a plan irregular structure. I applied the forces vector s=M*#934;. I want to know why the analysis in one of two possible analysis direction generates a Capacity Curve similar to a "accelerogram".
I had this problem in several models.

Thanks
Annamaria

Dear Annamaria,

You obviously are making a mistake of some sort, such as e.g. visualising the force-displ curve in the direction perpendicular to the loading, or something else..
