Abstract:

 This paper suggests a novel lateral load-resisting solution for RC high-rise reinforced con-crete frames using superelastic SMA wires as friction dampers. The suggested SMA-friction damper has some advantages, such as an easy-to-configure and affordable application, in ad-dition to being able to control the frictional energy dissipation components mechanism in line with the design procedure based on the suggested effectiveness thanks to its self-centering SMA wires. With the least amount of SMA use, it may produce hysteretic behavior and an intense tendency for self-centering. The research used two distinct design modescommon and with the recommended damperto construct two tall, 18- and 22-story RC frames. Ten farfield earthquakes were studied using OpenSees software in a nonlinear time history fashion. Eighteen and twenty-two-story reinforced concrete frame high-rises were designed in two distinct ways: normally and with the recommended damper. Aside from the major advancement in ductility, the lateral strength and stiffness gave an exceptional capacity for self-centering, resulting in a substantial decrease in most drift and persistent distortions in the structure. The studys findings showed that the suggested damper may improve the RC frames structural performance while using the fewest bracing spans and money.
