A Review : Retrofitting of Multi-Storey Structures in Seismic Zone IV Using Dampers

In light of rapid urbanization and the constraints on horizontal expansion in densely populated cities, the development of high-rise buildings has become a practical necessity. With the increasing demand for vertical construction, it is imperative to assess the structural performance of tall buildings under seismic forces. Earthquakes represent one of the most critical natural hazards, often imposing highly destructive loads on built infrastructure. Structures located within high seismic risk zones are especially susceptible to severe damage or total collapse. To mitigate these risks and enhance structural resilience, various retrofitting techniques and supplemental damping systems are employed. These interventions aim to improve the building’s capacity to withstand seismic events. This study specifically undertakes a seismic analysis of a multi-storey building situated in Seismic Zone-II and Zone-IV, in accordance with relevant design standards, to evaluate its dynamic response and structural behavior under earthquake loading conditions.
