Using numerical simulation via wave finite element method to study the effect of the station surrounding on the strong-motion recordings

Abstract

The Bajiao and Hanzeng station, which obtained the large strongmotion recordings in Ms8.0 Wenchuan Earthquake, were determined as investigating objects. The ANSYS software was used for establishing two-dimension finite element model of the soil layers for Bajiao station and the soil-structure interaction for Hanzeng station. The ground motion of two stations was simulated in the status of earthquake strike, after setting artificial boundaries, meshing models, considering soil nonlinearity and inputting seismic oscillation in the base. Finally, how the valley-terrace and high communication tower affect the strongmotion recordings of two stations was evaluated. © Springer-Verlag Berlin Heidelberg 2012.
