COMPARATIVE STUDY OF CONVENTIONAL AND SEISMICRESISTANT BUILDING STRUCTURES

Earthquakes are among the most destructive natural hazards affecting buildings, infrastructure, and human life. The performance of a building during an earthquake depends on its structural configuration, construction materials, foundation conditions, lateral load-resisting system, ductility, and quality of workmanship. Conventional building structures are generally designed primarily to resist gravity loads and other loads specified by applicable design requirements. In contrast, seismic-resistant structures are specifically designed and detailed to withstand earthquake-induced forces and deformations while maintaining structural stability. This research paper presents a comparative study of conventional and seismic-resistant building structures with respect to structural behaviour, earthquake resistance, construction cost, ductility, energy dissipation, safety, and long-term performance. The study is based on a review of earthquake engineering principles, relevant building design standards, and established structural design practices. Important seismic-resistant techniques, including shear walls, ductile detailing, cross-bracing, base isolation, and energy-dissipation devices, are discussed. The comparison indicates that properly designed and constructed seismic-resistant buildings can significantly improve life safety and reduce the likelihood of catastrophic structural failure during earthquakes. Although some seismic protection systems may increase initial construction costs, their benefits can include reduced damage, lower repair requirements, and improved resilience. The study emphasizes the importance of appropriate structural analysis, compliance with applicable building codes, skilled construction, and professional inspection.
