Impact of structural parameters on seismic performance of RC columns

This study aims to analyze the seismic behavior of reinforced concrete columns, based on various factors such as compressive strength, slenderness, and longitudinal reinforcement ratios. These factors are crucial in determining the ductility, strength, stiffness, and energy dissipation of reinforced concrete columns. The study examines the impact of different compressive strength, slenderness, and longitudinal reinforcement ratios on the seismic performance of reinforced concrete columns. To conduct the analysis, the FE computer program Seismo-structure was used to evaluate a series of reinforced concrete columns experimental tests. Special attention was given to selecting models for concrete, confined concrete, and steel components to accurately capture the behavior of the specimens. The results showed good agreement between experimental and analytical data in terms of lateral force-drift relationships and damage prediction.
