Benefits of technology

This patented technical solution described in this patents allows for better resistance against buckleings than traditional methods like stainless steels alone. It also includes various feature improvements made possible through dual-Ytrue Anti-Buckling Support (ADS) technology. Overall, these new solutions aim at providing more efficient protection while reducing costs associated with conventional ways used to protect structures during severe events.

Problems solved by technology

This technical issue addressed in this patents relates to improving the durable structure for resistive bearings without causing them losing their effectiveness due to buckled overload caused by high levels of pressure applied on one side (the inside) while being subjected to heavy loading repeatedly.

Abstract

The invention discloses a double-core multi-steel-tube all-steel buckling-restrained brace with double yield points. The buckling-restrained brace has double yield points, is high in seismic energy dissipation capacity and bearing capacity, and can meet the requirement for support bearing capacity of high-rise and long-span buildings under the earthquake action. According to the technical scheme,the buckling-restrained brace comprises an inner core tube and an outer core tube, wherein the inner core tube is made of low-yield-point steel, and the outer core tube is made of high-yield-point steel. The inner core tube is sleeved with the outer core tube, and a set gap exists between the inner core tube and the outer core tube; the two ends of the inner core tube and the two ends of the outercore tube are fixed to end connecting plates, the inner core tube sleeves an inner restraining sleeve, one end of the inner restraining sleeve is fixed to one of the two end connecting plates, and the other end of the inner restraining sleeve is suspended; an outer restraining sleeve sleeves the outer core tube, one end of the outer restraining sleeve is fixed to the other one of the two end connecting plates, and the other end of the outer restraining sleeve is suspended.
