Dear All,
I'm asking a very rudimentary thing. When we define property, How does staad use this? Does it only account for weight calculation? How does it account the stiffness of members? It seems to me staad accounts individual member stiffness's for their respective deflection instead of the structure as a whole. I did single line model of a portal pier frame with a stiff pier and given the size as 11m(wide) and 1.5m(thick). Even then it showed deflection of the piercap over the pier shafts which shouldn't. Logically deflections should be beyond the edges of pier shaft.
