Hengshui Zhanhe Engineering Rubber Co., Ltd. supplies buckling restrained brace (brb) and related engineering rubber products to contractors, distributors and infrastructure projects worldwide. A metallic yielding damper whose steel core yields in both tension and compression, dissipating seismic energy while the surrounding restraint prevents buckling.
This article explains the working principle, main types, typical applications, installation points, selection criteria, standards and frequently asked questions about buckling restrained brace (brb), and is intended for engineers, purchasers and project managers.
A metallic yielding damper whose steel core yields in both tension and compression, dissipating seismic energy while the surrounding restraint prevents buckling.
Working principle: The product works through elastic deformation and mechanical interlock to provide reliable sealing or load transfer.
Buckling Restrained Brace (BRB) is manufactured and inspected according to applicable national and industry standards. Hengshui Zhanhe Engineering Rubber Co., Ltd. carries out batch inspection before delivery, and inspection certificates together with third-party test reports (where required by the project) can be provided.
Typical standards applied to this product family include Chinese national and transportation industry standards; equivalent international standards can be referenced upon request.
A: Yes. A BRB contributes axial stiffness, so the lateral stiffness rises and the natural period shortens, which in turn increases the seismic force. The number and position of braces must therefore come from a global analysis, with both storey drift and the capacity of adjacent members checked.
A: No. Products tested to GB/T 37307 provide a cumulative plastic deformation capacity of not less than 200 times the yield displacement, so dozens of cycles at design displacement can be sustained. After an event beyond the design level, however, the core and connections should still be inspected and assessed.
A: It is designed for the same life as the main structure, with no mandatory replacement interval. Routine work is mainly anti-corrosion: coatings are generally checked and touched up every 15 to 20 years, and grout-filled units should be checked for cracks at the ends of the restraint.
Prices are quoted per brace set and built up from four items: the tonnage of the yielding core (low-yield steel costs more than Q235B), the restraint unit (steel tube plus grout), gusset plates and high-strength bolts, plus shop drawing work and third-party testing. A 2000 kN class unit with connections typically runs well above ten thousand RMB; the final figure is calculated from the approved shop drawings and the required yield force.
Packing: standard export packing (woven bags, pallets or wooden cases). Delivery terms: EXW, FOB, CFR, CIF or DAP as agreed. Payment terms: T/T, L/C or other terms subject to negotiation.
