摘要

摘要: 提出了一种易于快速装配且承载耗能能力优异的新型屈曲约束型装配式梁柱节点。该节点由带悬臂梁段钢管柱、中间梁段、屈曲约束连接装置组成,悬臂梁段与中间梁段之间通过屈曲约束连接装置进行连接。该节点在保证结构塑性损伤可控的同时,有效提升了结构的延性。基于有限元模拟手段对8个算例进行拟静力分析,通过研究不同参数对节点力学性能以及破坏模式的影响规律,明晰了影响节点承载耗能能力及屈曲约束效果的关键参数。结果表明:随着翼缘盖板厚度及强度的增大,节点承载耗能能力显著增强;随着外置翼缘盖板加劲高度增大、内置翼缘盖板与腹板连接件间距减小、以及腹板连接件加劲程度增大,节点的屈曲约束效果显著增强;高强螺栓数量过少会使翼缘盖板过早发生滑移,进而影响节点的承载耗能能力。

Abstract: A new type of prefabricated beam-column joint with buckling constraints is proposed, which has better energy dissipation capacity and is easy to repair after earthquakes. The joint consists of a steel tube column with cantilever beam and an intermediate beam. The cantilever beam and the intermediate beam are connected by a buckling constraint connection device, which can effectively improve the ductility of the structure while ensuring the plastic damage control. The quasi-static analysis of eight cases with different parameters was carried out by finite element simulations to study the influence of different parameters on the mechanical properties and failure modes of the joint, and then the key parameters affecting the bearing energy dissipation capacity and buckling constraint effects of the joint were determined. The results showed that the bearing energy dissipation capacity of the joint increased significantly with the increase of the thickness and strength of the flange cover plate. As the stiffening height of the outer flange cover plate increased, the spacing between the inner flange cover plate and the web connector decreased and the stiffening degree of the web connector increased, the buckling constraint effect of the joint could be significantly enhanced. Too few high-strength bolts would cause premature slip of the flange cover plate, which would affect the bearing energy dissipation capacity of the joint.
