摘要
通过采用快速动力加载方式,对2个传统风格建筑钢-混凝土组合梁-柱节点进行试验研究,获得了该类型节点的恢复力特征曲线、骨架曲线等抗震性能指标及加载全过程破坏特征。研究结果表明:采用钢-混凝土组合结构的传统风格建筑具有优良的抗震性能;相对比单梁-柱节点,双梁-柱节点的承载力刚度较高,滞回曲线更饱满,但其延性性能略低于单梁-柱节点;位于外围檐柱的双梁-柱构造形式具有与圈梁相类似的可加强结构整体性能的作用。研究结果可为传统风格建筑在实际工程中的应用提供有益的参考。
By using a fast dynamic loading method,two traditional style steel-concrete composite beam column joints were tested and studied,and the seismic performance indicators such as the restoring force characteristic curve,skeleton curve,and the whole process failure characteristics of the joints were obtained.Results show that the traditional style building with steel-concrete composite structure had excellent anti-seismic performance.Compared with single-beam column joint,the double-beam column joint had higher bearing capacity stiffness and fuller hysteretic curve,but its ductility performance was slightly lower than that of single-beam column joint.The double-beam column structure form located in the outer eave column had a role similar to the ring beam,and thus could enhance the overall performance of the structure use.The research results can provide useful reference for the application of traditional style architecture in practical engineering.
