| 摘 要： | 阐述文献[1]的第二部分。第一部分在Ba ant Z.P.等人提出的混凝土微平面模型的基础上引入钢筋的影响提出了一个适用于配筋混凝土的微平面动态本构模型。混凝土模型采用能够反映各种复杂受力行为并被试验充分验证的微平面模型,钢筋采用Cowper-Symonds型率相关的双线性模型。该模型可用于钢筋混凝土的静力和动力显式分析。这一部分将给出模型的显式算法和试验验证。

| 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. |
