[0002] Buckling-restrained braces are a new type of support. They are usually composed of an inner steel core, an outer restraint sleeve, and a non-bonded isolation material between the two. When an earthquake occurs, the process of causing the structure to vibrate through the movement of the ground is the process of inputting seismic energy into the structure. Under the same conditions, the higher the seismic intensity at the location of the structure, the stronger the ground movement, and the greater the energy input into the structure by the earthquake. The seismic energy input into the structure is usually converted into kinetic energy, elastic strain energy, hysteresis energy dissipation, and viscous damping energy dissipation of structural vibration. Traditional UHPC buckling restrained braces generally use a sleeve structure on the outside, which on the one hand increases the overall production cost, and on the other hand, due to its large size, it increases the difficulty of transportation.
