Nonlinear Dynamic Analysis Of A Reinforced Concrete Frame By The Boundary Element Method

Direct dynamic analysis of reinforced concrete frame buildings taking into account the nonlinear and plastic properties of materials by the finite element method is connected with the solution of a system of solving equa-tions of very high order. This is due to the fact that it is necessary to split the beams and columns that form the structure into a large number of finite elements, since the deformation properties of concrete are different in the compressed and stretched zones, as well as in the loading and unloading zones. In this paper, we propose a meth-od for investigating nonlinear spatial oscillations of a flat reinforced concrete frame, based on the method of boundary elements, which leads to a much smaller amount of computational work.
