主 题：Numerical simulation OpenSees geotechnical earthquake soil liquefaction seismic response
摘 要：The OpenSees computational platform has allowed unprecedented opportunities for conducting seismic nonlinear soil-structure interaction *** the geotechnical side,capabilities such as coupled solid-fluid formulations and nonlinear incrementalplasticity approaches allow for representation of the involved dynamic/seismic *** paper presents recent research that facilitated such endeavors in terms of response of ground-foundation-structure systems using advanced material modeling techniques and high-performance computing *** numerical results are shown for large-scale soil-structure systems,and ground modification liquefaction *** addition,graphical user interface enabling tools for routine usage of such 3D simulation environments are presented,as an important element in support of wider adoption and practical *** this context,Performance-Based Earthquake Engineering(PBEE)analysis of bridge-ground systems is highlighted as an important topical application.
