Abstract

In recent decades, the dual systems of steel moment-resisting frames and RC shear walls have found extensive application as lateral load-resisting systems for high-rise structures in seismically active areas .This paper investigated the effectiveness of tuned mass damper (TMD), viscous damper, friction damper, and the lead-core rubber bearing in controlling the damage and seismic response of high-rise structures with concrete shear walls. Five buildings (10, 15, 20, 25, and 30-story) with passive seismic control systems were analyzed in OpenSees using 50 seismic records. The structural responses (acceleration, drift, displacement, velocity, and base shear) were adopted as the criteria. The criteria were nondimensionalized by defining a measure to establish a relationship between the inputs (ground motions) and outputs (structural responses). In the end, the Multi Criterion Decision Making (MCDM) method was employed to rank the passive seismic control systems and select the best one. The results showed application of the multiple-criteria decision-making methods in selecting a seismic upgrading strategy and earthquake engineering.
