(Please visit the site to view this file)Dear All,
I am developing a full 3D model of a bridge pier. Which has a pile foundation, on top of it is a circular pier and then a piercap. pier cap is modelled using plate elements and the loads are applied on the nodes of the plates. however, I get an instability warning, which I need some assistance to get rid of. the STAAD model is attached herewith for your review.
