Seismic performance refers to the ability of a structure or infrastructure to withstand and remain functional during an earthquake. Researchers in this area study the behavior of buildings, bridges, dams, and other structures under seismic forces, as well as develop strategies to improve their performance and reduce the risk of damage or collapse during earthquakes. This research involves the use of advanced analytical and experimental techniques to assess seismic hazards, model structural response, and design mitigation measures. The goal of seismic performance research is to enhance the resilience of buildings and infrastructure to seismic events, ultimately saving lives and minimizing economic losses.
