is it possible to model a diaphragm slab in Sofiplus or in Text editor. I would like to have a slab which has infinitely rigid inplane stiffnes. Thanks.
Hey, as a variant you can try to increase the inplane stiffness of the entire group during calculation like this:
+PROG ASE urs:3 HEAD LINEAR ANALYSIS CTRL OPT SOLV 4 LC 1,2 grp2 2 quea 100 $ factor = 100 for group № 2 END
