摘要:本文首先介绍了动力分析的求解方法，显式方法和隐式方法各自的优缺点。随后介绍了PKPM-SAUSAGE软件中对于梁、柱、剪力墙和楼板的模拟方法。由于时间步长和模型精细化处理后导致计算规模的增加，PKPM-SAUSAGE软件采用CPU+GPU并行计算技术，同时优化模型网格质量，实现了动力弹塑性分析效率的提升。
Abstract: Firstly, solving methods for dynamic analysis are introduced, which can be largely classified into explicit integration method and implicit integration method, and their advantages and disadvantages are also introduced. Secondly, the simulation method of beam element, column element, shear wall element and slab element in PKPM-SAUSAGE are introduced.Because of the small integration time step and detailed modeling, the amount of calculation will be increased largely."CPU+ GPU" parallel computing technology is used in PKPM-SAUSAGE, and the mesh quality of model is also optimized, which improves the efficiency of dynamic elastoplastic analysis.
