Local stress of key members of frame beams and columns supporting walls of the girder transfer floor under rare earthquake was analyzed using ABAQUS software. The stress state and plastic deformation of builtin rebars, builtin steel and concrete in the members were analyzed. Results show that the preliminary design of beams and columns of the girder transfer floor is safe, which satisfies the bearing capacity under the moderate earthquake and the stress and deformation requirements under the rare earthquake.Keywords:highrise frame shear wall structure; transfer structure; bearing capacity; FEM analysis作者简介：毛蓉方，硕士，Email:bryanmao@126.com。参考文献［1］涂敏.高层框支剪力墙结构设计实例分析［J］.四川建材,2011,37(4):47\|48.［2］徐培福,戴国莹.超限高层建筑结构基于性能抗震设计研究［J］.土木工程学报,2005,38(1):14.［3］GB 50011—2010 建筑抗震设计规范［S］.北京:中国建筑工业出版社,2010.［4］刘伟庆,王曙光,杜东升，等.常州凯悦中心11#楼弹塑性分析及抗震性能评估报告［R］.南京:南京工业大学建筑技术发展中心,2011.［5］ABAQUS user’s manuals version63 ［M］.Rhode Island: Hibbitt, Kmtgsoll & Sorensen, Inc.,2002.［6］ABAQUS,Inc.
