Theory of complex stressed states in design standards

Abstract

The analysis of the work of natural structures of the domes from laminated wood and numerous preliminary calculations have shown the possibility of saving materials by reducing the height of a cross-section of meridional ribs. It is especially effective while designing the cladding as enclosing structures in collaboration with the elements of the frame (ring and meridional edges). Multiple static indetermination of such structure allows its non-linear work and the redistribution of efforts under uneven loads. In this case, the sheetings take a significant part of efforts that occur in the shell, and the edges are underloaded. Numerical computer calculations in real-time mode at a step-changing unilateral load are carried out taking into account its seasonal variations during 5.4years. The VAT of all elements is investigated. For the analysis of the frame, the calculation is performed by the method of an integral module, which allows controlling the strength resistance of the structure at any time of its operation.
