COMPARATIVE STRUCTURAL PERFORMANCE OF RC FRAME BUILDING BASED ON DUCTILITY VS DAMPING

Abstract

Earthquake is one of the inevitable natural hazards posing significant risks to structures, making it crucial to enhance their resilience and performance. This thesis explores the effects of varying ductility and damping on the seismic performance of building structures. Ductility, referring to the ability of structures to undergo inelastic deformation while maintaining strength, has been recognized as a critical factor in improving structural performance during earthquakes. This study emphasizes the shift towards ductility-based design techniques in India following the Bhuj earthquake in 2001. The primary objective of incorporating ductility in building structures is to ensure sufficient energy dissipation and deformation, thereby preventing brittle damage during seismic events. Additionally, the use of passive damping devices offers an alternative approach to energy dissipation. These devices effectively dissipate energy while limiting structural elements from reaching the plastic range. Through a comparative analysis, this study examines the impact of varying ductility and damping on structural performance. Various parameters are examined, including the influence of ductile detailing and the incorporation of passive damping devices such as dampers. By evaluating these factors, a comprehensive understanding of their effects on structural response is obtained. The study findings provide valuable insights into the significance of ductility and damping in enhancing structural resilience to seismic forces. This knowledge contributes to the optimization of design techniques, enabling the creation of safer and more resilient structures in earthquake-prone regions.
