A three-dimensional elasto-plastic dynamic response procedure for concrete-faced rockfill dams
International Journal of Distributed Sensor Networks, 2018 Equivalent linear dynamic analysis is the primary method of analysis for concrete-faced rockfill dams during earthquake. However, this method cannot be directly used to estimate permanent deformation during earthquake, which is important to evaluate the ...
