![عکس صفحه اول مقاله: Research of Influence of Soil Strength Failure on the Initial Seismic Action Transformation Research of Influence of Soil Strength Failure on the Initial Seismic Action Transformation](/preview/png/5030271.png)
The article examines the base - foundation slab system joint work with the nonlinear nature of the work and potential loss of base soil strength taking into account. As a source of the seismic action a three component accelerogram of an earthquake, rated to 9 points, was adopted. Base soil was modeled by means of a non-linear Mohr-Coulomb model, where failure conditions with specified limit values of shear strain and stress limitations with not working in tension soil have been entered. The calculation was made in LS-DYNA software package by a direct dynamic method with integration of motion equations using an explicit scheme. The article presents a comparison of results obtained with and without strength soil failure, as well as a research of original seismic impact transformation during weight loading facilities of the construction site was carried out.
