Efforts in statically indeterminate structures
Efforts in statically indeterminate structures
(OP)
Hello everyone,
I'm optimizing the cross section dimensions of a space frame structure, using analytical stress equations to get my constraint function and finite element analysis to compute the beam efforts (axial and shear forces, bending and torsional moments) for a given initial design. Objective function would be the cross section area, since the material is given.
Is this a valid approach? Are the efforts independent of the cross section properties, even for statically indeterminate structures? All beams will have the same dimensions, and the length of them is also fixed.
Thanks in advance!

but yes your approach seems reasonable. a truss (or space frame) are simple applications for FEA.
