摘要

研究目的: 通过某逆作法车站的粱柱节点内力和变形特性进行分析( 包括考虑各种工况的结构平面分析和三维分析，节点的分析和设计等) ，解决设计中的一些关键问题，并结合施工过程中结构变形和受力的实测数据，反馈和调整设计和施工工艺，保证工程设计和施工工作的顺利完成。

研究结论: 针对钢管混凝土柱和钢筋混凝土梁板结构节点的设计和施工，提出一种钢环板牛腿－钢筋混凝土环梁的组合结构形式，这种结构形式，利用钢环板牛腿承受剪力，利用钢筋混凝土环梁承受弯矩，受力明确，施工方便，且可在工厂加工，质量可靠。大大节省了节点施工的造价和时间成本。

Abstract

Research purposes: The calculation analyses，including 2D and 3D finite element analyses，joint analysis and design calculation on consideration of all working conditions，were made for the inner forces and deformation behavior of the joint of beam － column of a subway station constructed with top － down method to solve the key design problems． According to the measured data on the deformation and born load of the structure，the design parameters and construction procedures were adjusted to ensure the smooth completion of the design and construction．

Research conclusions: For the design and construction of joint of reinforcement concrete steel tube column and reinforcement concrete beam － slab structure，a structural form called combination structure of steel ring plate －reinforcement concrete ring beam is presented． In which，the steel ring plate bears the shear force and reinforcement concrete ring beam bears the moment respectively． This kind of joint has the following advantages: clear load distribution，easy construction and being produced in factory to ensure its quality and reduce the construction cost and time．
