I . a mtil ( iaxial elastic - plastic hardening - sofling constitutive model of concrete is proposed iii order to offer a nonlinear material model of concrete for space restoring force analysis of reinforced concrete members taking into account the softening behavior of concrete . the concrete material model is incorporated the elastic - plastic hardening fracturing constitutive model of concrete with the plastic - fracturing theory of concrete , modified without defining two loading functiomis , and based on five parameter power function failure criterion proposed by guo zheng - hai etc from tsingliua ( jniversity , or three parameter unified strength theory proposed by yu mao - hong from x ian iiaotong university
1 、将砼弹塑性硬化断裂本构模型与塑性断裂理论结合起来，并加以改进，但无需定义两个加载面，以清华大学过镇海建议的五参数幂函数或以西安交通大学俞茂宏建议的，参数统一强度理论作为砼的强度破坏准则，建立了砼多轴弹塑性硬化松驰本构模型，能为钢筋砼构件空间恢复力分析提供砼非线性材料模型，并能反映砼材料的软化段。
