摘　　要：针对钢纤维页岩陶粒混凝土(SFSCC)在冲击荷载作用下的黏弹性行为,采用含有损伤因子的ZWT本构模型进行描述,基于试验数据,确定了模型参数。根据分析结构与试验数据的比对,所建模型对SFSCC应力-应变曲线的弹性阶段的拟合效果较好,可以有效地描述SFSCC在弹性阶段的动力学响应过程。In light of the viscoelastic behavior of steel fiber shale aggregate concrete（SFSCC）under impact load,uses the damage factor of ZWT constitutive model describe it.Based on experimental data,parameters of a constitutive model were established.According to the analysis of structure with the experimental data,the model can fit the curve of the SFSCC stress-strain in elastic stage well.Itcan effectively describe the dynamic response process of SFSCC in elastic stage.
