Beam Section Temp
I recently send an inquiry about using temperature loading with stiffened plates and found that the stiffened plates were being restrained more than they should be. On the same project, I am having an issue with applying the beam section temperature to a beam which is supporting plate elements. The plates seem to be restraining the main beams, inducing a very large compression force into the beams. I tried to include element temperature on the plates to model the temperature on the top fibre of the beam. I have trying to model the Eurocode Approach 2, vertical temperature gradient model (see below).
The following shows the axial forces I am getting in the beams.
