Abstract
Many researchers study the seismic performance of shear wall embedded with reinforced concealed bracings, but not take the shape memory alloy bars concealed bracings into account. Quasi-static tests of a low shear wall with reinforced concealed bracings and a low shear wall with SMA bars concealed bracings are performed to study the seismic performance of the shear walls. Bearing capacity, stiffness, ductility, hysteretic energy and residual deformation of two specimens are researched and analyzed. The experimental results indicate that the SMA bars concealed bracings can increase the strength and ductility of the low shear wall considerably.
