Abstract

The invention relates to a self-reset anti-buckling supporting device which comprises an external constraint unit, an inner core and a reset device. The reset device is a reset spring component. The external constraint unit is used for containing the bending deformation of the inner core. The reset spring component is used for recovering the stretch or compression deformation of the inner core. The reset spring component can generate reactive force to conduct resetting without exerting prestressing force after a spring bears force and deforms, the residual deformation of the device under great shock can be reduced while the good energy consumption capacity of anti-buckling supporting is ensured, and then the preset resetting effect is achieved. Compared with prestress type self-reset anti-buckling supporting, the resetting function during supporting pull and press can be more conveniently achieved. The self-reset anti-buckling supporting device is simple in structure, low in price, convenient to machine and manufacture and beneficial to engineering application and popularization.

Description

technical field [0001] The invention relates to a novel energy-dissipating and shock-absorbing device for a building structure, in particular to a spring-type self-resetting anti-buckling support device. Background technique [0002] Traditional steel braces can increase the lateral stiffness and bearing capacity of building structures. However, under the action of strong earthquakes, the braces are prone to overall or local compression buckling, which significantly reduces the seismic performance of the structure. [0003] The anti-buckling support is based on the traditional steel support, and the outer restraint unit is used to restrain the bending deformation of the inner core, so as to realize the full-section yield energy dissipation of the energy-dissipating section of the inner core, and at the same time, no overall buckling occurs. Anti-buckling braces take into account the dual functions of traditional braces and metal dampers, which can effectively reduce the sei...
