摘要
对混凝土材料在静力和动力载荷作用下的损伤本构关系模型进行了评述.梳理了混凝土本构关系研究的历史脉络和逻辑脉络;归纳总结了在混凝土本构关系研究发展过程中具有代表性意义、并且对重大工程建设具有参考意义的若干混凝土静力和动力损伤本构模型.基于对混凝土材料非线性及随机性的理解和诠释,阐述了混凝土静力和动力本构关系研究的发展趋势.
For the research on dynamic failure of major civil structures,constitutive modeling of concrete is one of its key scientific issues.The constitutive models of concrete subjected to static action or dynamic excitation are reviewed in the present paper.The knowledge and development of constitutive models is discussed based on its historical developments and logical relations.Damage model of concrete which has been developed in recent years is summarized at macro and micro levels.The development trends of constitutive modeling for concrete are suggested on the basis of our understanding of essential physical properties of concrete,e.g.its nonlinearity and randomness.
