Overview

Finite element analysis reveals nonlinear buckling response in reinforced concrete columns, indicating design implications for enhanced infrastructure safety.

Key Points

  • Increasing slenderness ratio significantly decreases buckling capacity in reinforced concrete columns, particularly at λ = 120.
  • RCCs with slenderness ratios of 60 to 120 were analyzed, showing a 35% reduction in critical load at greater slenderness.
  • The analysis employed a combination of the Rayleigh–Ritz energy method and nonlinear finite element simulations in COMSOL Multiphysics.
  • Findings suggest the importance of accounting for slenderness effects in RCC design to improve safety and material efficiency.
