Abstract Earthquake-resilient structures have been widely recognized and applied in the seismic field of prefabricated steel structures due to their excellent performance. The prefabricated sinusoidal corrugated web steel beam-column joint (PSCWJ) with the earthquake-resilient design concept has been previously proposed. To study the impact caused by the bolt parameters on the seismic behavior of the new PSCWJ, five specimens were designed, with varying the number of flange connecting bolts, type of bolt holes, and interval between the middle bolts. A low cycle reciprocating load test and the finite element (FE) simulations were conducted on the specimens to determine the failure mode, energy dissipation capacity, ductility, hysteretic curves, sliding curves, strain curves, skeleton curves, and other main indexes on seismic performance. And the study indicates that the PSCWJ has excellent bearing capacity and seismic performance, the new prefabricated joint can realize the dual energy dissipation by buckling and sliding of the flange cover plate (FCP), and the number of flange connecting bolts directly determines the sliding load of FCPs. A rational interval between middle bolts can control the buckling load of FCPs and provide the joint with a satisfactory bearing capacity. The setting of slotted hole can increase the rotation and energy dissipation capacity of the joint. Further, the energy dissipation performance of the repaired specimens is stable under the low frequency constant amplitude loading, thereby ensuring that the PSCWJ can be used as a damper.

螺栓对抗震预制正弦波形腹板钢梁柱节点抗震性能的影响

摘要 抗震结构以其优异的性能在装配式钢结构抗震领域得到广泛认可和应用。具有抗震设计概念的预制正弦波纹腹板钢梁柱接头（PSCWJ）先前已被提出。为了研究螺栓参数对新型 PSCWJ 抗震性能的影响，设计了五个试件，改变了法兰连接螺栓的数量、螺栓孔的类型和中间螺栓之间的间距。对试件进行低周往复载荷试验和有限元（FE）模拟，确定破坏模式、耗能能力、延性、滞回曲线、滑动曲线、应变曲线、骨架曲线等抗震性能主要指标. 研究表明，PSCWJ具有优良的承载能力和抗震性能，新型预制接头可以通过法兰盖板（FCP）的屈曲和滑动实现双重耗能，法兰连接螺栓的数量直接决定了滑动载荷的 FCP。合理的中间螺栓间距可以控制FCP的屈曲载荷，为接头提供满意的承载能力。槽孔的设置可以增加接头的转动和耗能能力。此外，修复后的试件在低频恒幅载荷下的耗能性能稳定，保证了PSCWJ可以作为阻尼器使用。新型预制接头可以通过法兰盖板（FCP）的屈曲和滑动实现双重耗能，法兰连接螺栓的数量直接决定了FCP的滑动载荷。合理的中间螺栓间距可以控制FCP的屈曲载荷，为接头提供满意的承载能力。槽孔的设置可以增加接头的转动和耗能能力。此外，修复后的试件在低频恒幅载荷下的耗能性能稳定，保证了PSCWJ可以作为阻尼器使用。新型预制接头可以通过法兰盖板（FCP）的屈曲和滑动实现双重耗能，法兰连接螺栓的数量直接决定了FCP的滑动载荷。合理的中间螺栓间距可以控制FCP的屈曲载荷，为接头提供满意的承载能力。槽孔的设置可以增加接头的转动和耗能能力。此外，修复后的试件在低频恒幅载荷下的耗能性能稳定，保证了PSCWJ可以作为阻尼器使用。合理的中间螺栓间距可以控制FCP的屈曲载荷，为接头提供满意的承载能力。槽孔的设置可以增加接头的转动和耗能能力。此外，修复后的试件在低频恒幅载荷下的耗能性能稳定，保证了PSCWJ可以作为阻尼器使用。合理的中间螺栓间距可以控制FCP的屈曲载荷，为接头提供满意的承载能力。槽孔的设置可以增加接头的转动和耗能能力。此外，修复后的试件在低频恒幅载荷下的耗能性能稳定，保证了PSCWJ可以作为阻尼器使用。
