Description
Summary:Many of the built houses of residential building I-515/5 series have a number of characteristic damages and defects in load-bearing structures. There are tilts and biases of wall panels in their plane. To assess the technical condition of a residential building having these defections the shear rigidity of the wall panel is required to determine. However, there is a limited amount of research on this topic. Authors provided a numerical analysis by the finite element method of the stress-strain state of the wall panel in case given bias. The stiffness of the wall panel with the opening typical series has been determined at a given bias in its plane. The panel was calculated numerically using a nonlinear deformation model by the finite element method and analytically. The software package, LIRA-SAPR 2017, was used in this investigation. The calculation was carried out taking into account the nonlinearity and material creep. As a result, the fields of normal and shear stresses in the panel were obtained and the shear rigidity was calculated. The place of concentration of stresses was identified. The obtained results were analyzed and compared with the results of the calculation according to the norms. The analysis of the obtained results showed that a possible decrease of the actual stiffness of the panel should take into account against the calculated stiffness was obtained according to the standards.
