초록

This experimental study evaluated the seismic performance of a perforated masonry wall strengthened with a spring-damped steel-bar truss system. In the spring-damped steel-bar truss system, the spring dampers as variables were made with two types of steel: SS275 and SAE9254. An unreinforced masonry wall with a door-sized opening was strengthened with the un-bonded damping steel-bar truss system, and its performance was compared with unreinforced masonry walls and strengthened masonry walls by steel-bar truss system without a spring damper. Compared with the seismic performance of the unreinforced masonry wall, the energy dissipation, equivalent damping ratio, and m-factor of masonry walls reinforced with a spring-damped steel-bar truss system are approximately 2.18 times, 1.38 times, and 1.17 times, respectively, for the SS275 spring damper and approximately 2.35 times, 1.27 times, and 1.20 times, respectively, for the SAE 9254 spring damper. It is considered that the spring-damped steel-bar truss system significantly improved the seismic performance of the masonry wall. However, there is little difference in the reinforcement effect based on the steel type.
