I have a build a model of a concrete slab system in RISA 3d as a plate submeshed into 1'2" plates. I have a few steel beams that were installed 15 years ago and we are attempting to determine the load transfer to these beams.
My beams are drypacked to the bottom of the slab in real life, and in my model I have them connected every 2-3 feet with a pinned compression only member.
These plate elements are 8" thick (based on the slab) but I cannot find anywhere to enter any crack factor for the slab. Is this done automatically based on the material? Or do I have to modify the E or thickness of the slab to model this more correctly?
Thanks in advance!
