[摘要]近年來(lái)，隨著加固加層改造建筑日趨增多，國(guó)內(nèi)專家學(xué)者對(duì)該領(lǐng)域的研究也逐漸增多。本工程建成后即遭遇汶川地震，本文利用有限元軟件Midas Gen，對(duì)這一高層加固加層改造項(xiàng)目（5層+15層）在遭遇蘭州波、汶川波等地震波時(shí)進(jìn)行了大震作用下的計(jì)算分析，驗(yàn)證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.

Keywords : high-rise; strengthening and adding storey; Wenchuan earthquake; seismic analysis
