摘　　要：依据轻骨料混凝土单轴全应力-应变关系曲线,获得轻骨料混凝土损伤塑性模型的单轴应力-非弹性应变关系、单轴应力-开裂应变关系、损伤值-非弹性应变关系与损伤值-开裂应变关系,利用数值方法模拟轻骨料混凝土单轴压缩试验,结果表明,采用损伤塑性模型获得的有限元计算模拟值与试验拟合值吻合较好。According to uniaxial stress-strain curves of the lightweight aggregate concrete,uniaxial stress-inelastic strain curves,uniaxial stress-cracking strain curves,damage-inelastic strain curves and damage-cracking strain curves were obtained.Uniaxial compression experiment was simulated by numerical method,the results show that the values calculated by finite element method using damaged plasticity model can meet the ones obtained by experiment well.
