应变率下混凝土单轴受压本构关系试验研究

Research on experiment of constitutive relation of concrete uniaxial compression under strain ratio

通过试验对混凝土的动态性能进行了研究,分析了考虑应变率下混凝土单轴受压本构关系,得出五种混凝土在不同加载速率下的抗压强度、峰值应变、弹性模量的提高百分比。

The paper researches the dynamic performance of the concrete by the experiments,analyzes the constitutive relation of the concrete uniaxial compression under the strain ratio,and concludes the improvement percentage of the compressive strength,the peak strain and the elastic modulus of the five types of concrete under various loading rates.
