摘要

摘要: 针对既有干式连接梁柱节点构造复杂以及缺乏系统研究等问题,提出了一种蝶形耗能连接件装配式梁柱节点。首先,基于所提出节点的构造形式,分别依托现浇钢筋混凝土结构和螺栓连接钢结构梁柱节点的既有试验数据,采用ABAQUS程序建立相应的数值模型,通过对比分析验证数值计算方法和模型参数的准确性;在此基础上,建立了蝶形耗能连接件装配式梁柱节点数值模型,对其施加低周往复荷载,并通过与现浇节点对比分析,研究了该新型节点的抗震性能及主要影响因素。最后,对节点进行了优化设计,建立了具有该节点的框架结构整体模型,对其抗震性能进行了评估。结果表明:蝶形耗能连接件装配式梁柱连接节点滞回曲线整体形态饱满,耗能性能良好;蝶形耗能连接件装配式梁柱连接节点的力学性能会因高强螺栓预紧力大小及拼接钢板接触面摩擦系数大小不同而产生显著差异;采用优化后节点构建的整体结构模型,其地震位移响应略大于现浇框架结构体系,但整体抗震性能满足设防需求。

Abstract: Considering the complexity and the lack of systematic research for existing dry-connection beam-column joints, a prefabricated beam-column joint with butterfly-shaped energy consumpution connectors was proposed. Firstly, based on the structural form of the proposed joint, relying on the existing test data of cast-in-place reinforced concrete beam-column joints and steel structure joints connected by bolts, the corresponding numerical models were constructed by ABAQUS. The numerical calculation method and model parameters were verified by comparative analysis. On the basis, the model of the prefabricated beam-column joints with butterfly-shaped energy consumpution connectors was constructed, and quasi-static loading was applied to the joint. The seismic performance and main influencing factors of the new joint were studied by comparing with cast-in-place joints. Finally, the joint was optimized. The overall frame structure model with the joints was constructed, and its seismic performance was evaluated. The results indicated that the overall shape of hysteresis curves for the prefabricated beam-column joint with butterfly-shaped energy consumpution connectors was full and the energy dissipation performance was good. The mechanical properties of the prefabricated beam-column joint with butterfly-shaped energy consuming connectors would vary significantly due to high-strength bolt pretension and friction coefficients of splice steel plates. The seismic displacement response of the overall structure model constructed by the optimized joint was slightly larger than that of the cast-in-place frame structure system, but the overall seismic performance could meet the requirements of earthquake fortification.
