Investigate effects of the core distance from confining concrete on behavior of buckling restrained braces

Due to disadvantages of seismic behavior in conventional braces in term of low plasticity and asymmetric hysteresis curve in tension and compression and pinching which reduces the energy dissipation rate, Buckling Restrained Braces (BRBs) have been proposed as a new generation of bracing system. Thi...
