传统风格建筑钢-混凝土组合梁-柱节点动力循环荷载试验研究

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。

Experimental study on Chinese traditional style architecture lintel-column joint with steel-concrete composite structure under dynamic cycle loading

Based on the experimental of Chinese traditional style architecture lintel-column joint with steel-concrete composite structure under dynamic cycle loading, the failure characteristics and seismic behavior of the specimen are researched, which including the failure characteristics, skeleton curves, mechanical behavior such as the load-displacement hysteretic loops, load carrying capacity, degradation of strength and stiffness, ductility performance. The results indicate that the Chinese traditional style architecture with steel-concrete composite structure has good seismic performances. Compared with lintel-column joints, loading capacity of dual lintel-column joint is higher, and the hysteretic loops of the latter is in plump-shape. However, the displacement ductility coefficient of latter is little less than lintel-column joints. and the effect of eave column which locate in dual-lintel-column joint is similar to ring beam which can enhance the the whole performances of building structures. The research results presented can be used as reference on the application of Chinese traditional style architecture in practical engineering.
