Assembly type self-resetting buckling restrained brace
The invention relates to an assembly type self-resetting buckling restrained brace. The assembly type self-resetting buckling restrained brace mainly comprises an energy-consuming inner core, an inner pipe, an outer pipe, a connecting piece, an end plate, two groups of prestressed steel strands and a disc spring resetting device. The inner pipe and the outer pipe are force transmission parts of a resetting system and are also restraining parts of the energy-consuming inner core, so that the energy-consuming inner core does not need to be independently provided with the restraining parts, and the material consumption is reduced; the energy-consuming inner core is connected with the inner pipe and the outer pipe through self-tapping screws, so that the brace is convenient to assemble and replace after an earthquake; the resetting system is formed by connecting the two groups of prestressed steel strands and the disc spring resetting device in series, so that the deformation capability of the brace is greatly enhanced; after a disc spring combination in the resetting system is pressed under the action of external force, the supporting rigidity is increased, so that deformation concentration among structural layers can be prevented, the deformation among the structural layers is more uniform, and the collapse resistance of the structure under the action of a rare earthquake or even a very rare earthquake is effectively improved.
本发明涉及一种装配式自复位屈曲约束支撑，主要包括耗能内芯、内管、外管、连接件、端板、两组预应力钢绞线和碟簧复位装置。内管和外管既是复位系统的传力部件，又是耗能内芯的约束部件，使得耗能内芯不需要单独设置约束部件，节省了材料用量；耗能内芯与内管和外管通过自攻螺丝连接，便于支撑装配和震后更换；复位系统由两组钢绞线和碟簧复位装置三者串联而成，极大增强了支撑的变形能力；复位系统中的碟簧组合在外力作用下压并后，支撑刚度增大，可以防止结构层间变形集中，使结构层间变形更加均匀，有效提高结构在罕遇地震甚至极罕遇地震作用下的抗倒塌能力。
