RC shearwall pushover stability problem

Post by Jfoyian »

Hi all,

I am doing pushover analysis on RC shear walls but I guess I have stability problems in taller buildings (like 8 or 12 story ones) because the curve has many fluctuations and peaks. How can I improve the model to make it stable and get a reasonable curve?

Thanks

have you looked at the examples scripts?
example 5 and higher have parts in their script on dealing with such problems.
