Abstract

This paper represents Part Ⅱ of a two-part study in which a microplane constitutive model for reinforced concrete is developed. In Part Ⅰ[1], the model is proposed based on microplane model for plain concrete by considering the contribution of reinforcement. The constitutive model of Cowper-Symonds considering strain rate effect is adopted for steel. In Part Ⅱ, the explicit numerical algorithm is formulated. The model is verified by comparisons with test data available in the literature and comparison results show that the model presented in this paper can predict various mechanic property of reinforced concrete properly.
