Frictional energy dissipation type buckling-restrained brace
The invention relates to a frictional energy dissipation type buckling-restrained brace, which belongs to the field of seismic control of building structures. The frictional energy dissipation type buckling-restrained brace comprises a restraining member (1), a piston (2) and an energy dissipation core (3). The piston (2) is arranged at the middle of the energy dissipation core (3), the restraining member (1) sleeves the surface of the piston (2), the restraining member (1) is fixed at one end of the energy dissipation core (3) through an end plate (4), and connecting steel plates (5) are arranged at both ends of the energy dissipation core (3). Since the invention arranges the piston in the conventional buckling-restrained brace, the frictional energy dissipation mechanism is introduced. When inter-story displacement takes place in a structure, the energy dissipation core can be plastically deformed to dissipate energy, at the same time, the energy dissipation core and the restraining member shift relatively, the piston fixed on the energy dissipation core and the restraining member move relatively, energy is dissipated by the friction between the piston and the restraining member, and thereby the energy-dissipating capability of the buckling-restrained brace is effectively enhanced.
