Angle steel energy dissipation self-resetting coupling beam section rotating around vertex and application thereof
The invention discloses an angle steel energy dissipation self-resetting coupling beam section rotating around a vertex, which is connected between main structural beams of a required eccentric support steel frame and comprises a steel coupling beam section, a shape memory alloy rod and energy dissipation angle steel, the two ends of the steel coupling beam section are connected with a main structural beam of the eccentric supporting steel frame through energy dissipation angle steel, a shape memory alloy rod parallel to the steel coupling beam section is arranged in the steel coupling beam section and provides self-resetting tension, the shape memory alloy rod extends out of the end of the steel coupling beam section to be connected with the main structural beam, and long-strip-shaped holes are further formed in the end plate faces of the two ends of the coupling beam in the height direction of the coupling beam. The shape memory alloy rods penetrate through the long-strip-shaped holes and are prevented from being broken under the action of shearing force. According to the self-resetting energy dissipation coupling beam section, energy dissipation of the structure is guaranteed while self-resetting is achieved, and self-resetting performance and energy dissipation capacity are provided for an eccentric supporting steel frame structure.
本发明公开了绕顶点转动式角钢耗能自复位连梁段，自复位耗能连梁段连接于所需偏心支撑钢框架主结构梁之间，自复位耗能连梁段包括钢连梁段、形状记忆合金杆和耗能角钢，钢连梁段两端通过耗能角钢与偏心支撑钢框架主结构梁连接，钢连梁段内设有与钢连梁段平行的形状记忆合金杆，提供自复位拉力，形状记忆合金杆伸出钢连梁段端部与主结构梁连接，连梁两端端板面沿其高度方向还开设有长条孔，形状记忆合金杆穿过长条孔，避免其受剪力作用发生断裂；本发明的自复位耗能连梁段在实现自复位的同时，保证了结构的耗能，为偏心支撑钢框架结构提供自复性能和耗能能力。
