1. The problem statement, all variables and given/known data Hi, I need some help analysing this frame. First of all i bellive its hard, if not impossible, to get as detailed results by hand calculations as my softwear CSI Sap2000. Becourse of shear and axial deformation. Is it possible to obtain the stiffness matrix of this frame at all, or do i need to look at different methods. Can you pleas tell me where to ask if this is wrong forum? Thanks, most sincerly! 2.
