Seismic Response Analysis of Different Soil Types With Equivalent Linear Analysis Method

Abstract

In this study; With DEEPSOIL v7 software, seismic behavior analyzes of a region were made with 1D, “Equivalent Linear Analysis Method”. The method that offers the closest solution to the reality in the solution of engineering problems is the nonlinear solution method. However, it is very difficult to obtain and analyze the necessary parameters. For this reason, this method was chosen, which is not difficult to solve and gives the closest results to the nonlinear solution. Analyzes were made in the direction of whether the soil profile will absorb the earthquake in the event of a possible earthquake or, on the contrary, will increase the earthquake effect and transmit it to the building foundation. As a result of the analysis, the peak acceleration values were calculated and defined with acceleration-time-depth graphs. In this study, in which the seismic responses of different types of soil structures were investigated, it was observed that the soil structure was non-linear, the shear wave velocity value was an important parameter in determining the dynamic behavior of the soil, and the damping ratio of the soil increased with the increase in the shear wave velocity value.
