［提要］  利用ABAQUS軟件實現(xiàn)了復雜高層建筑結構的彈塑性時程分析，將梁、柱和剪力墻的彈塑性在材料的應力應變層次上精確模擬。通過工程實例，研究了彈塑性模型在地震時程中的變形及受力特點，得到結構構件截面的應力時程、應變時程、塑性應變時程，實時地反應結構受力性能，并驗證了整個方法的可行性。同時得到了截面在時程分析過程中的應力應變滯回曲線。

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.
Keywords:elastoplasticity; dynamic time history analysis; plastic strain; hysteresis curve; ABAQUS
