capacity curve of a 2D infilled frame
Posted: 20 Jun 2011, 23:23
Hi,
I’m applying a static pushover analysis on a 2D infilled frame, with three bays and three storeys. When I obtain the capacity curve of the infilled structure, initially I observe a high peak of base shear. After the value of base shear decreases sharply and then the curve is similar to a bare frame curve.
Is this behaviour related to the type of the structure? Or am I doing any mistakes?
Thanks
Nicoletta
