摘要
将屈曲约束支撑(BRB)引入装配式混凝土柱-钢梁(RCS)组合结构中,提出一种装配式混凝土柱-钢梁-屈曲约束支撑(P-RCS-BRB)组合结构连接节点,以适应当前抗震设计的更高要求。该节点不仅能实现全装配,还能有效降低支撑所带来的开合效应影响。采用经验证的有限元模拟分析方法,对此节点的抗震性能进行分析,结果表明:该节点具有高承载、可装配、震后无损伤等特点,满足强节点连接的设计要求和大震弹性的抗震目标,有助于实现结构的震后功能可恢复。
In this paper,the buckling restrained brace(BRB)is introduced into the fabricated reinforced concrete column-steel beam structure(RCS).A joint of fabricated reinforced concrete column-steel beam-buckling restrained brace(P-RCS-BRB)composite structure is proposed to adapt to the current seismic design of higher requirements.This connection type of the node can not only realize the full assembly,but also effectively reduce the opening and closing effect brought by the support.The seismic performance of the joint is analyzed by using the verified finite element simulation method.Numerical analysis results show that the joint has high bearing capacity,strong energy dissipation capacity and recoverable function.It is expected that the node can meet the design requirements of strong joint connection and the seismic target of large earthquake elasticity,which is helpful to realize the function recovery of structure after earthquake.
