Comparative Study on Seismic Analysis of Multistorey Building Using STAD Pro - A Review

Abstract

Abstract: This literature review provides a comprehensive analysis of the behavior of buildings with concave corners in earthquake-prone areas. The study emphasizes the impact of irregularities in building planning, particularly in concave corners, on the structural performance during seismic events. Findings from various research studies highlight the necessity for detailed and comprehensive analyses, including both linear and non-linear dynamic analyses, to accurately understand the behavior and response of such structures. The research underscores the significance of regular building configuration to enhance earthquake resilience, especially in regions susceptible to seismic activity. Buildings with concave corners are found to be more vulnerable to earthquake damage compared to structures with regular configurations. Additionally, larger structures and longer overhangs are shown to result in increased stress and pressure on the reentrant corner region. Overall, the literature review emphasizes the importance of further research in the field of concave corner irregularities to develop effective seismic design and mitigation strategies. A deeper understanding of the behavior and response of buildings with concave corners will contribute to the development of safer and more resilient structures in earthquake-prone areas. Comprehensive and advanced analyses are recommended to accurately assess the performance of such buildings and to establish guidelines for their proper design and construction.
