 Abstract
Analysis of ten one-fifth scale models of reinforced concrete piers using the two dimensional finite element method was presented in this paper. The predicted behaviors from present analysis were compared with test result. The material models used in the finite element analysis are based upon the biaxial state of stress. This model assumes the orthogonal anisotropy that the reinforced concrete element with several cracks shows an anisotropic properties each in normal and parallel direction to the crack. The degradation of strength and stiffness due to the crack generation, yield of tension and compressive reinforcements, bond effect with reinforcement, and shear transfer at crack plane were considered in the analysis. Also, the realistic consideration about the compressive behavior of the reinforcement after yield gave rise to better simulation of inelastic mechanical behavior of reinforced concrete member.
