Keywords:Dynamic pushover analysis, Reinforced concrete frame, Seismic assessment, Performance evaluation, Lateral load patterns, Ductility capacities
This review article presents a comprehensive investigation into the dynamic pushover analysis of a reinforced concrete frame. The study delves into the essential aspects of seismic assessment and performance evaluation of structures using this advanced analytical technique. With seismic events posing significant threats to structures, accurate assessment methodologies are crucial for ensuring the safety and reliability of buildings. The paper begins by introducing the concept of pushover analysis, which involves subjecting the structure to a series of lateral loads, representing seismic forces, in a progressively increasing manner. The behavior of the reinforced concrete frame under these loading conditions is studied in detail to understand its seismic response and performance characteristics. Different parameters, such as lateral load patterns, strength distributions, and ductility capacities, are explored to assess their impact on the overall seismic behavior of the structure. Furthermore, the review article discusses the key advantages and limitations of dynamic pushover analysis in comparison to traditional linear static approaches. Various numerical models and software tools used to conduct such analyses are critically reviewed, along with case studies to illustrate real-world applications and outcomes. This review article emphasizes the significance of dynamic pushover analysis as an effective seismic assessment tool for reinforced concrete frames. The insights gained from this study can aid researchers, engineers, and professionals in making informed decisions for the seismic design and retrofitting of structures, ultimately contributing to safer and more resilient built environments.
