that FEM looks like gross overkill for that structure.
have you analyzed it by hand so you have something to compare the FEA results to?
do you not have a local mentor?
hmm, surely there is steel rebar in the building? you need to account for that in the analysis.
otherwise post some pictures of the areas with singularities, with stresses and boundary conditions. I suspect the boundary conditions are too rigid.
yes, in aerospace structural analysis.
thermal loads from FEA are often high because FE models tend to be over stiff (missing lots of local flexibilities).
what type of model - beam, plate, shell, solid?
how are you defining CTEs?
how are you defining boundary conditions?
So I’m in a different industry, and have watched (read about) the ASD vs LRFD debate for some time, with a mixture of amusement and confusion. As a note, ASD is essentially what we use in aerospace. Reading the start of the paper linked above, the only difference seems to be that ASD uses one...
if you are in a seismic zone, those cripple walls are notorious for falling over in an earthquake, and thus need to resist shear loads from the building above.
