Abstract
The problem about composite loading of a thin-wall design of the open structure(profile), asymmetrical on geometrical and stiffness to the characteristics is reviewed. Adopted in this work the computational scheme is lower the solution allows to refuse a hypothesis about absence of shift in a middle surface adopted V.Z. Vlasov [2]. As in reduced activity the system of authorizing equations is constructed, which one has some differences from known equations of V.Z. Vlasov a rule (situation,position) of a point also is determined, concerning which one there is a turn of cross-section, and which one in the given activity and is hereinafter called as center of rotation.Download
