梁铰区搭接节点抗震试验研究

Seismic Experimental Study of Connection with Splice Bar in Beam Hinge Zone

通过对梁铰区采用纵向搭接的钢筋砼中节点的抗震性能试验研究，探讨了梁铰区搭接连接的可行性．重点分析了不同的搭接型式对梁铰区的弯曲延性、刚度退化、粘结锚固及耗能性能的影响，提出了此类节点最佳锚固型式及锚固长度的设计建议．

A new type of RC frame interior connection with splice bar in hinge zone of beam is proposed and feasibility of the connection is discussed on the basis of test under cyclic loading. The test results of 4 specimens show the influence of different styles.of splices on behavior of strength, stiffness loss, bend ductile, bond, anchorage and energy dissapating. Suggestions on the design of best style of splices and anchorage length are developed.
