[摘要] 本文簡要介紹了SAUSAGE軟件所采用的“GPU +CPU”并行計算手段，詳述其動力彈塑性時程分析的方法，包括顯式分析方法、鋼材和混凝土本構模型、纖維梁單元與分層殼單元、結構模型構建過程及分析步驟。隨后選取某帶加強層的框筒結構，采用SAUSAGE與ABAQUS進行罕遇地震作用下動力彈塑性時程對比分析，以研究該結構體系的抗震性能，并驗證SAUSACE的正確性與高效性。

(1 RBS Architecture Engineer Design Associate, Guangzhou 510170, China; 2 Guangzhou Scientific Computing Consultants Co., Ltd., Guangzhou 510170, China)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.
