This paper presents a numerical strategy to model nonlinear damage behavior of RC members based on level of material. The first part of the paper presents a numerical model of the RC member based on the Timoshenko multifiber beam elements and non-linear damage constitutive laws for concrete, and the effective three dimensional fiber beam-column element model is developed for the nonlinear damage analysis of RC members with VUEL subroutine based on ABAQUS/Explicit platform. In the second part, a nonlinear damage analysis for RC members is established by analyzing the sections of fiber beam column elements, and the member damage index through statistical analysis of concrete fibers damage is defined in the extreme section of beam elements, which can describe the nonlinear damage behavior of RC members under any loadings. Accuracy of the model is identified preliminarily by comparing with the analysis results of solid elements, the results shows that it seems now possible to use this approach to investigate numerically the nonlinear damage behavior of RC members based on level of material.
