| 摘 要： | 为了对型钢混凝土构件进行精细化建模分析,首先建立了仅依靠材料参数的混凝土本构关系以及损伤演化方程,根据型钢应变的发展以及屈曲影响,得到了型钢损伤本构模型.通过对型钢与混凝土粘结-滑移机理的进一步分析,进而建立了一种同时考虑粘结损伤和力学损伤的型钢与混凝土界面损伤模型,以合理考虑粘结-滑移对构件力学性能的影响.最后,对型...

| Abstract: | The newly proposed constitutive and damage evolution laws of concrete depending only on material parameters is obtained.The damage constitutive law for steel by taking into account the plastic train development and buckling effect of steel is established for the accurate numerical model of steel reinforced concrete(SRC) members.The bond-slip relationship between steel and concrete is analyzed.An interfacial damage model is established to consider the effect of bond-slip on the mechanical character of member... |
