I perform the Pushover analysis of 3D RC frame in SAP2000.1)How to bring the Push over curve through center of axis ? 2) Column hinge is not following the back bone curve after Yielding ,what it means ?
For the same model ,I added the brick infill diagonal strut with pin ends and tension limit zero.The stress strain curve for brick masonry is added in SAP2000.The element is modeled as displacement control .The modelling parameters are taken from FEMA356.
After pushover ,diagonal strut has not failed but rather frame elements failed,how is it possible ? Where the mistake is ?
