钢筋混凝土框架结构中防屈曲支撑连接节点的损伤控制

DAMAGE CONTROL OF CONNECTION JOINT FOR BUCKLING RESTRAINED BRASED IN RC FRAMES

  • 摘要: 为减轻防屈曲支撑节点板与混凝土梁、柱构件之间相互作用对连接性能和框架抗震性能的不利影响,针对混凝土框架结构中的防屈曲支撑提出一种非约束节点连接形式,并通过调整梁端配筋进行局部损伤控制,最大限度地保证连接性能。拟静力试验结果表明:建议的连接方法能够成功地转移梁端损伤部位,有利于提出连接节点的可靠性。

     

    Abstract: An unconstrained gusset connection is proposed for buckling restrained braces in reinforced concrete frame structures in order to eliminate the detrimental frame action because of the interaction between the gusset plate and the adjoining reinforced concrete columns and beams, which may impair both the connection performance and the aseismic performance of the structural system. The local damage control by means of adjusting the longitudinal rebards in concrete beams is also adopted to further ensure the performance of the gusset connection. The results of quasi-static tests show that the proposed damage control scheme is able to relocate the beam end plastic hinge to outside the gusset region and thus protect the connection from being deteriorated.
