Earthquake Response Analysis of Bridges with Soil-Structure Interaction and Pier Nonlinearity

지반-구조물 상호작용과 교각의 비선형성을 고려한 교량의 지진응답해석

With the increasing possibility of earthquake occurrence, seismic safety of bridges has become one of the most important social issues in Korea. In this study, a nonlinear earthquake response analysis is carried out for a real bridge by incorporating soil-structure interaction and pier nonlinearity. The material nonlinearity of the bridge pier is realized by utilizing SAP2000 whereas the soil-structure interaction is analized in time domain by adapting KIESSI. The numerical results are compared to those of the models without considering the effects.
