ABSTRACT Through Experiment, we study the aseismic behavior of inserted reinforced concrete column-steel beam (RCS) composite joints. In order to design an RCS with endplate combination joint, we analyze simulation test joints on a basis of the static load test combining with finite element software ABAQUS. The numerical simulation results and the contract test results which include finite element simulation of load–displacement curve of bending moment–rotation curve and the components of yield sequence are basically the same as the experiment results. This uniformity verifies the reliability to use numerical simulation upon such problems. To compare with the ordinary reinforced concrete structures, the new type of inserted RCS composite joints is safer, and it presents a better seismic performance under the static load of the beam end. After we use numerical simulation to study the influential factors of six kinds of RCS combination of static performance including the axial compression ratio, steel insert length, the thickness of endplate, the ratio of the width of column section and beam section, the column concrete grade and four kinds of joint structure, we found that it does not only well perform on mechanical aspect but also is simple and convenient on the structure and construction of RCS composite nodes.

钢筋混凝土柱-钢梁侧缝抗震性能研究

摘要 通过试验，我们研究了插入式钢筋混凝土柱-钢梁（RCS）组合节点的抗震性能。为设计具有端板组合接头的RCS，在静载试验的基础上，结合有限元软件ABAQUS对仿真试验接头进行分析。包括弯矩-转动曲线载荷-位移曲线有限元模拟和屈服序列分量在内的数值模拟结果和合同试验结果与试验结果基本一致。这种一致性验证了在此类问题上使用数值模拟的可靠性。与普通钢筋混凝土结构相比，新型插入式RCS组合节点更安全，在梁端静荷载作用下表现出更好的抗震性能。
