Abstract: In the paper, a nonlinear creep model analyzing the multilayered composite structure was proposed. The model predicts a time-dependent behaviuor of composite made of the layers undergoing the age-variable properties. A solution adopted deals with iterative analysis of Volterra integral equation implying a particular generalization of the principle of superposition for the nonlinear creep strain of the layers. A three-layered concrete structure subjected to a sustained loading was considered for the sake of demonstration of the technique proposed. Increase in layer strengths and modulii of elasticity due was also investigated to analyse the possible failure of layers.
