预埋钢梁节点改为现浇混凝土节点的可行性分析

某钢筋混凝土结构,局部区域原设计采用钢梁+组合楼板结构,后改为现浇混凝土梁板.在混凝土柱侧钢板预埋件已经施工完成的情况下,为了解决混凝土梁与钢板预埋件之间的有效连接,采用在钢板预埋件上焊接钢牛腿,并将梁纵筋与钢牛腿焊接的连接方式,从而实现将混凝土梁支座内力传递到钢牛腿上.通过结构整体建模计算以及支座节点内力分析,验证该节点连接方式能够满足结构受力要求,同时为了保证该节点连接的可靠性,从结构构造上提出了若干加强和保证措施.
Feasibility Analysis of Replacing Embedded Steel Beam Joints with Cast in place Concrete nodes
In a reinforced concrete structure,steel beam plus concrete floor slab was used in the original design of the local area,then the steel beam has been changed into concrete beam.After the construction of the steel plate embedded in the side of the frame column was completed,in order to solve the effective connection between the concrete beam and the steel plate embedded part,the steel bracket is welded on the steel plate embedded part,and the longitudinal bar of the beam is connected with the steel bracket,thus,the internal force of the bearing of the concrete beam can be transferred to the steel corbels.Through the whole structure modeling calculation and the bearing node internal force analysis,it is verified that the connection mode of the node can meet the structural force requirement,and at the same time,in order to ensure the reliability of the connection of the node,some strengthening and guaranteeing measures are put forward from the structure structure.
