摘　　要：进行了施工阶段混凝土强度、弹性模量的计算,并利用有限元分析软件MADIS/GEN对施工阶段的钢筋混凝土结构进行了结构动力特性、反应谱和弹性时程的抗震对比分析,研究了地震对施工阶段的建筑物的影响。结果表明:按照规范正规设计和施工的高层框剪结构,施工阶段遭遇地震作用时,其主体结构随施工进度会遭遇不同程度的破坏。The concrete strength and the variation of elastic modulus in construction stage were calculated. Through the finite element analysis software MIDAS/GEN, the dynamic characteristics changes of construction stage and the same constraints in existing building structure were researched, as well as the mode decomposition response spectrum, elastic time-history analysis. In the end,earthquake influence to the main part of the project construction was studied. It shows that when encountering earthquake action in construction stage,high rise building with frame shear wall structure, which according to a formal specification of design and construction, whose main part will meet varying degree damage with the construction progress.
