Assembly type steel-wood buckling restrained brace with vertically embedded FRP reinforcement
The invention discloses an assembly type steel-wood buckling restrained brace with vertically embedded FRP reinforcement, including a core material, a peripheral restraint, an unbonded material or an air layer, wherein the core material includes connecting sections, transition sections, a core work section, a stop clamp and a reinforcing plate, two ends of the core work section are connected with the connecting section by the transition sections, the stop clamp is arranged at the middle of the core work section, the transition sections are arc-shaped, connection bolt holes are formed in the connecting sections, the peripheral restraint includes two pieces of core material up-down laminated wood and two pieces of core material dual-side laminated wood, the two pieces of core material up-down laminated wood are transverse in wood grain direction and the two pieces of core material dual-side laminated wood are transverse in wood grain direction, and a vertically embedded carbon fiber plate is arranged between the core material up-down laminated wood and the core material dual-side laminated wood. The assembly type steel-wood buckling restrained brace with vertically embedded FRP reinforcement can be used in earthquake regions, and is convenient to repair after the earthquake and reduce earthquake damages. The assembly type steel-wood buckling restrained brace with vertically embedded FRP reinforcement has wide application prospect in middle-high wood structure buildings.
