Anti-seismic energy-consumption reinforcing device and method for reinforced concrete beam-column joint
The invention relates to an anti-seismic energy-dissipation reinforcing device and method for a reinforced concrete beam-column joint. The device comprises a first shape memory alloy assembly, a second shape memory alloy assembly and a third shape memory alloy assembly. The first shape memory alloy assembly is located on a beam in a beam-column joint area. The second shape memory alloy assembly is mounted on a column in a beam-column joint area and is connected with the first shape memory alloy assembly; the two ends of the sliding friction damper are connected with the first shape memory alloy assembly and the second shape memory alloy assembly respectively. The rigidity of the beam column joint is guaranteed through the shape memory alloy T-shaped plate, meanwhile, energy consumption is achieved through the slidable sliding friction damper, excessive displacement between the beam columns is limited, and therefore the effect of resisting progressive collapse is achieved, automatic resetting of the joint after deformation can be achieved, and the safety of the joint is improved. Therefore, the reinforcing effect of the reinforced concrete beam-column joint is enhanced.
本发明涉及一种钢筋混凝土梁柱节点抗震耗能加固装置与方法，该装置包括：位于梁柱节点区域的梁上的第一形状记忆合金组件；安装在梁柱节点区域的柱上且与所述第一形状记忆合金组件相连接的第二形状记忆合金组件；以及两端分别连接所述第一形状记忆合金组件和第二形状记忆合金组件的滑动摩擦阻尼器。本发明在在用形状记忆合金T形板保证了梁柱节点的刚性的同时，通过可滑动的滑动摩擦阻尼器实现耗能并限制梁柱之间的过大位移，从而起到抗连续倒塌的作用，并能实现变形后节点的自动复位，进而增强钢筋混凝土梁柱节点的加固效果。
