| 摘 要： | 提出了一种螺栓端板连接的钢梁-钢筋混凝土柱新型组合节点,为了研究这种新型节点的抗震性能,对两组足尺试件进行了模拟地震加载试验。试验结果表明,两组试件均具有较高的承载力、良好的延性和耗能能力,它们的延性系数都超过4。由于试件JD02采用了比试件JD01更厚的端板、更大直径的高强螺栓,破坏形态由JD01的螺栓断裂变成JD02螺栓断裂同时还发生梁铰破坏。结果表明,JD02具有更高的承载力、更大的延性和更好的耗能能力。由试验结果可看出,这种新型节点具有优良的抗震性能;影响其抗震性能的主要因素是高强螺栓的预拉力和端板的厚度。

| Abstract: | A new type of end-plate bolted connection with steel beam and reinforced concrete column is investigated, and two full-scale model connections were tested under simulated seismic loading. Experimental results show that this new type of composite connection has satisfactory seismic performance with high strength and excellent ductility as well as good energy dissipation capability. The thicker endplate and stronger high-strength bolts were utilized in specimen JD02 than specimen JD01, resuhing a hie.her strength and more ductile behavior. |
