Self-reset buckling-restrained brace device
The invention relates to a self-reset buckling-restrained brace device. The self-reset buckling-restrained brace device comprises an outer portion constraint unit, an inner core and a reset device, wherein the reset device is a reset spring component, the outer portion constraint unit is used for constraining the bending deformation of the inner core, and the reset spring component is used for recovering the stretching or compression deformation of the inner core. The reset spring component adopted by the self-reset buckling-restrained brace device uses the reactive force generated after a spring is stressed and deformed to conduct reset, a pre-stressing force is not needed to be exerted, on the basis that the good energy-dissipating capacity of a buckling-restrained brace is guaranteed, the residual deformation of the buckling-restrained brace under a large earthquake can be reduced, and the predetermined reset effect is achieved. Compared with a pre-stressing force type self-reset buckling-restrained brace, by means of the self-reset buckling-restrained brace device, the reset functions in stretching and pressing of a brace can be achieved more conveniently. The self-reset buckling-restrained brace device is simple in structure, low in price, convenient to machine and manufacture and convenient for project popularization and application.
