Hi,
There seems to be an error, when calculating the utilization with the “utilization of beams” node for SHS-profiles specifically. The results for “Beamview Utilization” and “Utilization of Beams” are different. Note that I’m checking the cross-section. Buckling is turned off. When doing a simple hand calculation based on Eurocode the “Beamview Utilization” seems to be the correct one. “Utilization of Beams” gives a slight underestimation of around. This does not occur for other profile types that I tried (HEA, HEB and IPE). In that case the result values are the same for both nodes. Also noteworthy: this error does not occur when the beam is subject to mere bending. See attachment below to see the simple model that I used to test this. Does anyone know where this discrepancy comes from? I think there might be an error in the code, that causes hollow sections to give the wrong result. Or is there maybe a Eurocode formula that I’m missing here?
