The purpose of the work is the further development of the numerical-analytical method of boundary elements for solving the problems of mechanics of deformed solid body, where there are no analytical solutions, and the development of scientifically grounded methods of finite-element analysis of structures in SOFiSTiK and ANSYS packages with all types of influence followed by their implementation. computational practice. Research methods - analysis of literary and own data; the use of differential equation theory, matrix theory, linear algebra methods, boundary element method, finite element method; computer modeling and calculations in modern engineering applications. The authors obtained new results for rectangular and circular orthotropic plates, cylindrical and inclined shells, plates with stiffening ribs, systems with distributed parameters; experimental researches of cross-beam systems, orthotropic plates, cylindrical shells; computational techniques have been developed for the SOFiSTiK and ANSYS complexes in two variants: interactively and in the form of an executable file. The research work results can be used both in the design of new structures and in the modernization of existing ones, as well as applied in the learning process. The advanced methods of analysis of structures used in construction, mechanical engineering, bridge construction, aviation, shipbuilding, military equipment, etc..
