Abstract In order to facilitate floor assembly and pipeline paving, this paper puts forward a new kind of prefabricated opening-web steel channel beam-column joint with double flange cover plates (POWSCBCJ) which is based on the design concept of plastic damage concentration and replaceable damage components. Six quasi-static reciprocating loading tests were carried out on four joints, and the hysteretic curves, skeleton curves, slip curves and strain curves of each specimen were obtained. The effects of thickness of flange cover plate (FCP), the quantity of connecting bolts and the bolts spacing of FCP and other parameters on the seismic performance and post-earthquake repairable performance of the joint are mainly investigated, and the post-earthquake repairable function, and fatigue performance of the joint under low-cycle reciprocating load are evaluated. Experimental study shows that this kind of joint has good bearing capacity, seismic performance and low-cycle fatigue performance. The joint can transfer the plastic hinge to the replaced FCP by strengthening the flange of the cantilever beam and weakening the FCP, so as to protect the major components such as beams and columns, and the joint function can be quickly repaired by replacing the energy dissipation components after earthquake; the repaired joint also has good bearing capacity and seismic capacity. Each design parameter has great influence on the bearing capacity and energy dissipation capacity of the joint.

双FCP抗震预制开孔腹钢槽钢梁柱节点试验研究

摘要 为便于楼板拼装和管道铺设，基于塑性损伤集中、可更换的设计理念，提出了一种新型的预制开孔腹板钢槽梁柱双翼缘盖板节点（POWSCBCJ）。损坏组件。对4个关节进行6次准静态往复加载试验，得到各试件的滞回曲线、骨架曲线、滑移曲线和应变曲线。主要考察了法兰盖板（FCP）的厚度、连接螺栓的数量和FCP的螺栓间距等参数对接头抗震性能和震后可修复性能的影响，以及震后可修复功能, 评估了接头在低周往复载荷下的疲劳性能。试验研究表明，这种接头具有良好的承载能力、抗震性能和低周疲劳性能。该接头通过加强悬臂梁的翼缘和弱化FCP，将塑性铰转移到更换的FCP上，从而保护梁柱等主要构件，通过更换耗能件可以快速修复接头功能地震后的组件；修复后的接头还具有良好的承载力和抗震能力。每个设计参数对节点的承载能力和耗能能力都有很大的影响。该接头通过加强悬臂梁的翼缘和弱化FCP，将塑性铰转移到被更换的FCP上，从而保护梁柱等主要构件，通过更换耗能件可以快速修复接头功能地震后的组件；修复后的接头还具有良好的承载力和抗震能力。每个设计参数对节点的承载能力和耗能能力都有很大的影响。该接头通过加强悬臂梁的翼缘和弱化FCP，将塑性铰转移到更换的FCP上，从而保护梁柱等主要构件，通过更换耗能件可以快速修复接头功能地震后的组件；修复后的接头还具有良好的承载力和抗震能力。每个设计参数对节点的承载能力和耗能能力都有很大的影响。修复后的接头还具有良好的承载力和抗震能力。每个设计参数对节点的承载能力和耗能能力都有很大的影响。修复后的接头还具有良好的承载力和抗震能力。每个设计参数对节点的承载能力和耗能能力都有很大的影响。
