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) (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 …
