Abstract

Two problems of vertical propagation of seismic SH wave through nonlinear media is considered. The seismic wave is half sine pulse-like wave, prescribed in the soil. First, the problem of single layer (or one-story building) sitting on a half-space is considered. The response is studied on 1-D numerical model of uniform shear beam. The response of the layer depends upon: -- excitation properties (the amplitude and the duration of the prescribed input half-sine pulse), -- layer's nonlinear properties (the yielding strain and the nonlinear modulus), -- the ratio of impedances of layer and half-space. Second, the response of a recorded building in Van Nuys, Los Angeles metropolitan area, is considered. The response is studied on 1-D multi-layered shear beam model. Although the 1-D model is the simplest numerical model, it gives excellent agreement with the recorded response.
