All-steel double-yield-point fracture-free buckling-restrained brace
The invention relates to an all-steel double-yield-point fracture-free buckling-restrained brace. The all-steel double-yield-point fracture-free buckling-restrained brace comprises a core unit, an outer restraining unit and connecting units at the two ends, wherein the core unit comprises a first yield steel plate and a second yield steel plate, the thickness of the first yield steel plate is smaller than that of the second yield steel plate, the length of a first core section is larger than that of a second core section, the outer restraining unit comprises a clamping steel pipe, a fixing pulling and connecting piece and a steel pipe clamping plate, the connecting units comprise inserting plates fixedly connected with the outer restraining unit, and the fixing pulling and connecting piece is of a set of connecting bolts. The all-steel double-yield-point fracture-free buckling-restrained brace is a staged buckling-restrained brace and has a fracture-free function, the buckling-restrained brace has a plurality of yield points through construction, and the buckling-restrained brace can yield and consume energy under small earthquakes; and by arranging an outer restraining unit limiting device, the plastic deformation of a working unit is limited, and the working unit is protected against fracture. Under the action of super-large earthquakes, the multi-yield-point fracture-free buckling-restrained brace cannot be fractured, and the application range of the buckling-restrained brace is greatly widened.
一种全钢双屈服点免断裂屈曲约束支撑，包括核心单元、外约束单元和两端的连接单元，核心单元包括第一屈服钢板和第二屈服钢板，第一屈服钢板的厚度小于第二屈服钢板的厚度，第一核心段的长度长于第二核心段的长度，外约束单元包括夹持钢管、固定拉接件和钢管夹板，连接单元包括与外约束单元固定连接的插板，固定拉接件为一组连接螺栓。本发明是分阶段屈服屈曲约束支撑，并具有免断裂功能，该防屈曲支撑通过构造使其具有多个屈服点，小震下即可屈服耗能，并通过设置外约束单元限位装置，限值了工作单元的塑性变形，保护工作单元不发生断裂。在超大震作用下，多屈服点免断裂防屈曲支撑不会发生断裂，大大的提高了防屈曲支撑的应用范围。
