| 摘 要： | 综合分析了传统的柱贯通型和梁贯通型两类钢筋混凝土柱-钢梁组合框架结构(RCS)节点及几种改进型RCS节点的构造特点及试验研究成果,归纳总结了其破坏形态与整体性能。在此基础上,将RCS理念与装配式建筑技术相结合,提出了一种基于钢接头的装配式组合框架结构节点,并进行了与RCS节点性能的有限元分析对比。分析结果表明,该节点表现出较高的承载力及延性变形能力,具有良好的抗侧性能,钢接头能有效保证节点的整体性,具有进一步研究与应用价值。

| Abstract: | Two types of reinforced concrete column-steel beam combined frame structure(RCS)joints of traditional column-through and beam-through type were analyzed,and the structural characteristics and experimental research results of several improved RCS joints were analyzed,and their failure mode and overall performance were summarized.On this basis,combining the RCS concept with the prefabricated building technology,a fabricated composite frame structure joint based on steel end connector was put forward,and the finite element analysis of the performance of RCS joints was analyzed.The results show that the proposed joint exhibits high bearing capacity and ductility,and has good anti-side performance.The steel end connector can effectively guarantee the integrity of the joint,which has further research and application value. |
