performance of reinforced cement concrete (RCC) and steel structures under seismic loads across various seismic zones using ETABS software. Representative RCC and steel structures are modeled and analyzed according to relevant codes and standards. Seismic loads corresponding to different seismic zones are applied, and key performance indicators such as base shear, story drifts, and modal characteristics are evaluated. The results are compared to identify the relative strengths and weaknesses of each structural system in varying seismic intensities. The findings provide insights into the seismic behavior of RCC and steel structures, enabling informed decision-making for structural design and construction practices. The research highlights the optimal structural system for specific seismic zones, considering material properties, construction techniques, contributing to enhanced seismic resilience of built infrastructure.

In this project, response spectrum analysis will be employed to investigate the seismic performance of reinforced cement concrete (RCC) and steel structures in various seismic zones. The response spectra used in the analysis will be derived from design codes and standards, reflecting the seismic hazard levels of the respective seismic zones under consideration.

1. INTRODUCTION Earthquakes pose a significant threat to the structural integrity and safety of buildings, particularly in seismically active regions. The devastating consequences of seismic events underscore the critical importance of designing structures that can withstand the loads and deformations induced by earthquakes. Reinforced cement concrete (RCC) and steel are two widely used structural materials, each with its unique properties and behavior under seismic loads. This research project aims to conduct a comprehensive investigation into the structural performance of RCC and steel structures in various seismic zones. The primary objective is to evaluate and compare the seismic response of these two structural systems when subjected to different levels of seismic intensity, ranging from low to high seismic hazard regions.
