[摘要] 本文简要介绍了SAUSAGE软件所采用的“GPU +CPU”并行计算手段，详述其动力弹塑性时程分析的方法，包括显式分析方法、钢材和混凝土本构模型、纤维梁单元与分层壳单元、结构模型构建过程及分析步骤。随后选取某带加强层的框筒结构，采用SAUSAGE与ABAQUS进行罕遇地震作用下动力弹塑性时程对比分析，以研究该结构体系的抗震性能，并验证SAUSACE的正确性与高效性。

Abstract: The parallel processing of "GPU +CPU"  adopted by SAUSAGE is introduced,  the elastic-plastic time-lustory analysis method of SAUSAGE is specified, include the explicit method, steel and concrete constitutive model, fibre beam element and layered shell element, the build process of structural model and analysis steps. Then a framed-tube structure with outriggers was selected as a study case, the elastic-plastic time-history analysis under the rare earthquakes is carried out by SAUSAGE and ABAQUS, in order to study the seismic performance of this structural system, and showed the correctness and efficiency of SAUSAGE.
