Abstract: The article analyzes current trends in the field of ensuring the stability of load-bearing building structures to avalanche destruction. The main approaches and methods used to improve the reliability of structures in possible emergency situations are considered. Controversial points are noted in the existing method of assigning an element, the removal of which can lead to an avalanche-like destruction of the entire structure. This algorithm is implemented using the finite element method in a geometrically and structurally nonlinear formulation, which makes it possible to take into account complex interactions within the structure under the influence of various loads. To more accurately simulate the behavior of the structure, correction functions are given that correct the local stiffness matrix of the core element used in geometrically nonlinear calculations. The algorithm is implemented in the MATLAB programming language. The article provides an example of using the proposed technique on the construction of a mesh truncated dome with a span of 50 meters along the larger axis.

Keywords: geometric and structural nonlinearity, finite element method, avalanche collapse, mesh truncated domes, reliability, survivability, probability of failure.
