| 摘 要： | 完成了7个高剪压比钢筋混凝土框架夹心节点试件的低周交变荷载试验,试验过程中夹心节点试件表现出较好的受力、变形、耗能性能和较高的位移延性,多数试件因节点剪切破坏失效,没出现核心区受压破坏的情况。虽然夹心节点的某些性能如梁筋的粘结滑移性能等相对传统节点更为不利,但其综合性能仍然能够满足结构抗震设计的要求。

| Abstract: | Seven reinforced concrete Beam-Column sandwich joint specimens were tested under cyclic load.The performances of these specimens consisting of loads resistance,deflection,ductility,displacement,energy dissipation could satisfy the requirement of structures for seismic design.The phenomena that concrete in joint region was crushed by axial load or eccentric load were never observed,and final failure for a multitude of specimens occurred by shear force.Though a few of performances such as beam bar anchorage capacity were not as well as those of traditional joints,it is feasible for sandwich joints used while establishing structures. |

| Keywords: | sandwich joints seismic resistant performance ductility failure mode beam bar anchorage capacity |
