Abstract

A simple constitutive model, quasi-visco-elasto-plastic constitutive model, was proposed considering viscoelasticity and viscoplasticity for fatigue analysis. Applicability to the concrete and RC member was investigated by introducing into three-dimensional Rigid Body Spring Model. As a result, the proposed model could simulate fatigue behaviors of both concrete and RC members although fatigue strengths were underestimated. The effectiveness of the discrete analysis with proposed model was also shown by evaluating of the fatigue failure mechanisms of RC members.
