Dear Zoi,

Thanks for your quick reply!

I took a copy of the same pushover model and changed the analysis type to eigenvalue analysis. Thus, everything is identical. However, I am still getting totally different modal frequencies and mode shapes from the two analyses!! I will send the two models to ...

Dear All,

Before doing a pushover analysis I did an eigenvalue analysis to verify the modal frequencies and mode shapes of the model. I specified the mass source to be from both element masses and additional mass elements. When I did the pushover analysis, I looked at the eigenvalue results and ...

Many Thanks Zoi. It works perfectly now. I really appreciate it.

Kindest Regards,
Nader

Dear Zoi,

Many thanks for the reply.

This is exactly what I did. However, I still clearly see that the three elements (two boundary elements and the web) are not acting together. Maybe there is something wrong with the way the software understands the definition of the rigid link in this ...

Thanks for the reply.
Yes, I did divide the wall over the height into several segments. Then, I tried using rigid links/ rigid diaphragm or Equal DOF joint constraints to join the columns to the walls over the height. When I run the analysis it seems that there is no any effect from those ...

Dear All,

I am trying to model a shear wall with boundary elements. It is easy to do so using the reinforced concrete rectangular wall section. However, I find it is a bit restrictive for my particular application. In fact, my walls are reinforced masonry and the boundary elements sometimes have ...
