Abstract
In this paper, a numerical study of the strain-stress state of a complex architectural and composite structure in the form of a Mobius strip, made of heavy structural concrete with polystyrene void formers, was carried out. The analysis of strain-stress state is carried out by the finite element method (FEM) in specialized software packages with additional processing of output data. The procedure for analyzing the strain-stress state of large volumetric FE models of building structures, taking into account the stress concentrators and the possibility of appearance, degenerate finite elements as a result of automatic triangulation, is given. Verification of the proposed algorithm by numerical and qualitative comparison of the results of calculations by different software packages was carried out. The fields of stress and displacement displacements obtained in different program packages showed sufficient convergence. The possibility of using this algorithm for the analysis of strain-stress state for other complex structures.
