Novel self-resetting buckling restrained brace
The invention discloses a novel self-resetting buckling restrained brace. The novel self-resetting buckling restrained brace comprises an outer sleeve, wherein an inner sleeve is slidably connected to the inner wall of the outer sleeve, end plates are connected to the inner wall of the inner sleeve and the inner wall of the outer sleeve in a lap joint mode, and a plurality of prestressed tendons are arranged on the surfaces of the two end plates. The outer sleeve, the inner sleeve, the prestressed tendons, a cross-shaped steel core, a square steel pipe and the end plates are arranged, and after an earthquake is over, the large self-restoring force of the prestressed tendons enables the left end plate and the right end plate to be close to each other, so that the outer sleeve which is welded to a first baffle and the inner sleeve which is welded to a first check block move away from each other relatively; and an energy dissipation component is a buckling restrained brace, under the action of tension and compression loads, the cross-shaped steel core yields, the earthquake energy dissipation effect is good, the technical experience of the buckling restrained brace is mature, and a reset system of the prestressed tendons is additionally arranged on the basis, so that the energy dissipation component can be restored to the initial state, and the energy dissipation component can still work normally after the earthquake action.
本发明公开了一种新型自复位约束屈曲支撑，包括外套筒，所述外套筒的内壁滑动连接有内套筒，所述内套筒的内壁与外套筒的内壁均搭接有端板，两个端板的表面设置有若干个预应力筋。通过设置外套筒、内套筒、预应力筋、十字形钢芯、方形钢管和端板，地震结束后，预应力筋自身很大的自恢复力使左右端板相对靠近，从而使第一挡板焊接的外套筒和第一挡块焊接的内套筒发生相对远离运动，该耗能构件为约束屈曲支撑，在受拉、受压荷载作用，十字型钢芯屈服，耗散地震能量效果好，且约束屈曲支撑技术经验较成熟，在此基础上增加预应力筋的复位系统，使耗能构件能恢复到初始状态，保证了本发明在地震作用后还能正常工作。
