Performance-Based Evaluation Techniques for Seismic Vulnerability Assessment of Reinforced Concrete Structures

Abstract

Performance-based evaluation methods are the key to determining the seismic resistance of reinforced concrete structures, to make them able to withstand seismic events. This study aims to develop advanced techniques for the seismic assessment of the structures, where structural integrity, deformation capacity, and energy dissipation mechanisms are key parameters. The entire study will be based on comprehensive analysis and simulation so that the behavior of the structure under the seismic load can be understood effectively and mitigation strategies can be developed. Through the integrated use of advanced computational models and seismic hazard scenarios, the study rates the performance of reinforced concrete structures in terms of displacement capacity, ductility, and overall structural response. Through the application of probabilistic seismic hazard assessment and fragility analysis, the research quantifies the seismic vulnerability of structures which in turn offers these insights for risk management and decision making. Besides, the research is carried out to develop novel retrofitting methods that improve the seismic resistance of existing RC structures considering parameters like material characteristics, structural geometry, and construction practices. The testing of the experiments and the numerical simulations are used to determine the effectiveness of the retrofitting techniques in the improvement of the seismic performance of the structures and to validate the effectiveness. These performance-based evaluation techniques offer a systematic method of assessing and reducing seismic vulnerability of reinforced concrete structures which is also a great contribution to the development of resilient infrastructure and enhancing the safety of the communities in earthquake-prone areas.
