Abstract
This paper presents a comprehensive seismic analysis of a G+4 reinforced concrete building using base isolation techniques. The study compares fixed-base and base-isolated structures using SAP2000 software and response spectrum method as per IS 1893:2016. Key parameters such as base shear, acceleration, displacement, and velocity are evaluated. Results show significant reduction in seismic forces in base-isolated structures. However, two parameters showed similar values due to input errors during modeling, which could not be corrected due to software license limitations. In earthquake-prone areas, designing and constructing buildings with seismic resilience is crucial for reducing structural damage and protecting human life. This paper explores a range of construction techniques aimed at improving earthquake resistance, with a particular focus on their effectiveness in lowering seismic risk. It assesses key factors such as structural behavior, material characteristics, and architectural design strategies that enhance a building’s ability to withstand earthquakes. The research includes a comparative evaluation of various structural systems, including base isolation, energy dissipation mechanisms, and reinforced concrete frameworks. Drawing from real-world examples across different seismic zones, the study analyzes how these methods have been implemented and their performance during actual earthquake events. The results emphasize the critical need to combine advanced engineering techniques with localized seismic data to enhance the structural resilience of buildings. The study also brings attention to the significance of cross-disciplinary cooperation among architects, structural engineers, and materials experts in creating comprehensive earthquake-resistant design strategies. In conclusion, this paper seeks to offer valuable insights into innovative approaches and best practices in seismic-resistant construction, serving as a useful reference for professionals engaged in developing durable infrastructure in seismically active regions.
