组合梁与混凝土剪力墙新型连接节点受力性能
Mechanic Behavior of a New Type of Connection Between Composite Beam and Concrete Shear Wall
【摘要】 以上海市浦东新区文献中心主楼组合梁与混凝土剪力墙新型连接节点为对象,通过模型试验和数值分析研究了大尺寸方钢与混凝土剪力墙的共同工作性能。结果表明,该类节点可以可靠地工作;理想的设计方案是在方钢上设置三个45°的三角形或梯形抗剪键;增大剪力墙的厚度和墙体中的配筋率可以有效地控制裂缝宽度;提高混凝土强度可增大节点的承载力。
【Abstract】 Based on the model tests and numerical calculation,mechanic behavior of connection between composite beam and concrete shear wall in the main building of Achieves Exhibition Hall of Pudong New District in Shanghai is studied.The results of research indicate that this type of connection can work reliably,the ideal design scheme for the main component of the connection,the square steel bar is setting three triangle or trapezium shear keys with a angle of 45° on the surface of the bar.By increasing the depth of shear wall and the ratio of reinforcement,the crack width in the wall can be controlled effectively.High strength of concrete can enhance the bearing capacity of the connection.
【Key words】 composite beam; square steel bar; concrete shear wall; connection;
