[摘要]近年来，随着加固加层改造建筑日趋增多，国内专家学者对该领域的研究也逐渐增多。本工程建成后即遭遇汶川地震，本文利用有限元软件Midas Gen，对这一高层加固加层改造项目（5层+15层）在遭遇兰州波、汶川波等地震波时进行了大震作用下的计算分析，验证了本工程在大震地震波作用下良好的抗震性能。

Abstract ：In recent years, with the increasing of strengthening and adding storey renovation construction, researches in the field by domestic experts and scholars have also gradually increased. The wenchuan earthquake is coming after the project completion.The transformation project(5 + 15 layer ) which in lanzhou, wenchuan earthquake wave and seismic wave is analysed by the soft wave of Midas Gen with finite element method .And this paper verifies the good auti-seismic performance under rare earthquake.
