Abstract
The pliability of dense joints of panel buildings is a necessary element of mathematical models of load-bearing systems. The malleability of the same type of connections working on the shift is determined. Experimental data and normative literature were used. The existing regulatory framework and experimental studies lead to a significant variation in the pliability vertical joints working for the shear. Connections such as welding of embedded parts, reinforced dowels usually work in the elastic region, but the use of deformation diagrams makes it possible to take into account the peculiarities of the work of butt joints, cracking, nonlinear work under complex loads. The malleability of joints was determined by the shear-displacement deformation diagrams. The parameters embedded in the calculated discrete-continuum model of the building's load-bearing system under standard static loading are determined by numerical modeling using a software package. The article uses the example of a specific series of panel buildings P-44 to compare the stress-strain state at different values of compliance. The forces in the panels of the building and deflections depending on the pliability of shear joints are given.
