Sustainability of walls of individual residential houses with a wooden frame

The aim of work. The stability of the walls of individual houses with a wooden frame and the stress-strain state of a single-story structure are investigated, and also problems of their strength and seismic resistance are considered. Solution technique. The development of a methodology for calculating small, simple in form individual houses, with the reinforcement of load-bearing walls by a frame, is described. The methodology includes the following stages: the creation of a mathematical model of structures; choice of the numerical method - the finite element method (FEM), which allows to take into account the structural features of the structure; carrying out calculations of buildings for specified loads. The choice of the finite element method is justified by the possibility of calculating a spatial model that takes into account the real geometry and structural features of the structure. Results. Using the spatial model allowed to take into account in detail the presence of the framework, and analysis of the stress-strain state revealed an increase in the rigidity of the structure with a skeleton, which indicates an increase in strength, stability, and seismic resistance. The connecting role of the skeleton is revealed, which consists in combining the elements of the structure into a single spatial system. The static effect consists in the perception of the rigid elements of the framework by the applied static load, which causes in them a slight deformation transferred to the piers between the frame elements. This leads to a uniform distribution and a general reduction in the level of stresses in the walls in comparison with the same stresses in walls without a frame
