［摘要］广州琶洲1401地块项目型钢混凝土转换层节点构造复杂，为了保证节点满足“中震弹性设计，大震不屈服”的性能要求，同时简化节点构造和施工，采用了节点三维实体建模的设计方法进行节点设计，并对节点进行了有限元分析，同时提出新的型钢钢板穿孔补强方案，通过试验证明了该方案是方便可行的。

Abstract: Due to the complicated construction of the transfer joint of Guangzhou Pazhou PZB1401 project, the design method of 3D solid modeling and finite element analysis of joint were adopted to guarantee the performance requirement, that is elastic design under intermediate earthquake and un-yield design under great earthquake. In addition, a new reinforcing method to perforated section steel plates of joint was proposed to simplify the construction of the joint. It is proved that the reinforcing method is convenient and feasible through tests.

Keywords: transfer joint; finite element analysis; perforated reinforcement
