OpenSees Concrete06 Material Test

Concrete06是基于Thorenfeldt曲线建立的考虑混凝土抗拉强度、非线性受拉硬化及受压性能的单轴本构。

  • 材料参数(Material Parameters

Concrete06C

(Figure from : http://opensees.berkeley.edu/wiki/index.php/File:Concrete06C.png )

fc:混凝土28天抗压强度(concrete compressive strength at 28 days );

e0:混凝土峰值强度对应的应变,即fc对应的应变(concrete strain at maximum strength);

n:受压应力—应变曲线的形状系数(compression shape factor);

k:峰值压应力后的应力—应变曲线的形状系数(post-peak compression shape factor);

alphal:定义受压残余塑性应变的参数(α1 parameter for compression plastic strain definition);

fcr:混凝土抗拉强度(tensile strength);

ecr:抗拉峰值应力对应的应变(tensile strain at peak stress);

b:受拉硬化曲线的指数(exponent of the tension stiffening curve);

alpha2:定义受拉残余塑性应变的参数(α2 parameter for tensile plastic strain definition)。
