［提要］  利用ABAQUS软件实现了复杂高层建筑结构的弹塑性时程分析，将梁、柱和剪力墙的弹塑性在材料的应力应变层次上精确模拟。通过工程实例，研究了弹塑性模型在地震时程中的变形及受力特点，得到结构构件截面的应力时程、应变时程、塑性应变时程，实时地反应结构受力性能，并验证了整个方法的可行性。同时得到了截面在时程分析过程中的应力应变滞回曲线。

Abstract:Nonlinear elastoplastic time history analysis for complex structures is realized by ABAQUS program.For members such as beams,columns and shear walls,elastoplastic behavior is modeled with material stressstrain curve.Seismic deformation and mechanical behavior are studied for a real project to show the structure loading capacity and prove the probability of the way,listing member sectional stress history,strain history,plastic strain history and member hysteresis curves.
