The influence of the ground's morphology on the seismic analysis with no integration errors

摘要

In order to find the influence of ground's morphology three models are used. One of the simplest models for simulating the soil stress-strain response during earthquake loading is the viscoelastic Kelvin-Voigt model. The first model is using a horizontal surface and for the other two models a circular shape was added or removed from the regular surface in order to generate imperfections to the concave or convex surface. After the first run integration errors are found and the results are shown in the paper. After analyzing the obtained results it the different between the models is clarified.
