THEORETICAL ANALYSIS AND COMPUTATIONAL METHOD FOR NON-UNIFORM TORSION OF THE THIN-WALLED SPATIAL HELICOID GIRDERS (PART 2 COMPUTATIONAL METHOD)

In this paper, based on the fundamental theory of the foregoing paper¹, a generalized three-dimensional element stiffness matrix of the thin-walled spatial helicoid girder and the corresponding equivalent nodal force vector subjected to uniformly distributed load have been developed by the principle of strain energy. Some numerical results have been compared with the reference 3 and reference 4 to identify it's credibility.
