Hi,
I'm trying to apply user defined wind loads on an irregular semi-rigid diaphragm, but I'm noticing that the loads with some eccentricity are being distributed in an unexpected manner. The loads are switching direction multiple times on the windward and leeward sides of the same diaphragm. Here's a screenshot:
The program generated eccentric wind loads seem to be more uniformly distributed but they're still switching signs along the same edge:
What version? I used to see this sometimes for slab edges that were very nearly (but not quite) parallel to the direction of the load.
