Seismic Analysis of Tall Structures Using Shear Walls and Friction Dampers: A Review

The increasing prevalence of tall buildings in urban areas, especially in seismically active regions, necessitates robust structural systems capable of withstanding lateral forces during earthquakes. Among various structural solutions, shear walls and friction dampers have emerged as effective components in enhancing the seismic performance of tall structures. This review presents a comprehensive analysis of the roles, advantages, limitations, and recent advancements in the use of shear walls and friction dampers for seismic mitigation. Shear walls significantly improve lateral stiffness and reduce inter-story drifts, whereas friction dampers provide efficient energy dissipation through sliding mechanisms. While shear walls contribute to structural rigidity, friction dampers excel in reducing vibration-induced damage without altering the building’s stiffness significantly. The review also explores hybrid systems that combine both technologies to optimize seismic response. The paper concludes with insights into future trends, including smart damping systems and AI-based optimization. This review serves as a valuable resource for researchers and engineers in designing resilient tall buildings against seismic hazards.
