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...
The article discusses a calculation technique for a reinforced concrete building with a braced frame on an earthquake. It allows to produce an adequate assessment of a of seismic stability level. A direct simulation of concrete, reinforcement and their binding with the help of volumetric and core finite elements is fulfilled. The paper presents the concrete work chart and considers mathematical models...
