This paper studies the seismic response of reinforced concrete (RC) columns, focusing on how damage develops and the failure mechanisms during biaxial bending. The behavior of RC columns is crucial for the reliability and safety of buildings, especially during unpredictable events like earthquakes. The research looks at the geometric and displacement features of RC columns under both uniaxial and biaxial cyclic loading. It discusses various confinement models for axial compression in column design, covering area-based, strength, and ductility analyses. The paper explores the reasons behind RC building failures, such as inadequate confinement, bond splitting or slipping, insufficient shear and flexural capacity, and irregularities in the design structure. It presents an experimental study on the behavior of RC columns under different failure scenarios, including earthquakes and heavy loads. The effects of biaxial loading on columns and 3D characteristics are assessed through evaluations of inelasticity and damage concentration. The study also looks at the shapes of columns and their displacement patterns when subjected to biaxial bending forces from two orthogonal directions. The findings enhance understanding of RC column behavior under extreme loads and offer insights for better design and construction practices to prevent structural failures during seismic events.
