| 摘要： | The problem of nonlinear pile foundation-superstructure interaction is addressed by adopting a substructure approach and developing appropriate time-domain methodologies for the analysis of each subsystem, as well as procedures to analyze the global system response. The need for nonlinear modeling and the importance of foundation dynamics to overall system response is established first by studying the response of the Painter Street bridge excited by the Petrolia Earthquake of 1994. Subsequently, the problem of a yielding superstructure on a linear foundation is studied. The superstructure is modeled by a two degree-of-freedom system that involves a Bouc-Wen model to simulate nonlinear behavior. Two different solution methods are developed to obtain the system response. |
