The Effects of Height on the Seismic Vulnerability of RC Frame Buildings

The effects of building height on the seismic vulnerability assessment of reinforced concrete (RC) frame buildings are an important consideration for structural engineers and designers. Since high-rise buildings have become more common in earthquake-prone regions in recent years, this topic has received significant attention because buildings’ dynamic characteristics change with the structure’s height. Several factors affect a building’s seismic vulnerability, such as its height, mass, and structural characteristics. This paper has discussed the various factors that influence the seismic performance of RC-frame buildings, such as the building’s strength and ductility, as well as the effects on the fragility curve due to an increase in the building’s height. Additionally, the paper has discussed the different seismic hazard levels (DBE and MCE) and how they impact the vulnerability of tall buildings. This paper’s findings will help structural engineers and designers understand the effect of building height on the seismic vulnerability assessment of RC-frame buildings, enabling them to design more resilient structures in earthquake-prone regions.
