Hello,
I am calculating a steel frame. I made load combinations in Maxima. I want to do stability check in bdk for steel but it gives me error ‘bdk is not applicable to superimposed load cases’ . How should I proceed further to analyse steel members for maximum values of the load combinations ?
Thank you.
BDK requires the point of application of the loads (top or bottom of the girder), but MAXiMA cannot provide this information.
The information from MAXiMA only includes internal forces. However, these are not coherent, since they always form an envelope.
