摘要
为建立一个含参数砌体本构关系统一模型,应用能量原理和损伤力学理论解释了砌体单轴受压过程中损伤能量与热量释放的关系,定义了损伤变量。通过选取的一个损伤函数,结合砌体轴压作用下应力-应变曲线的特征,提出了砌体受压含参数本构关系模型,并依据烧结页岩多孔砖砌体轴压试验结果,验证此含参数统一本构关系的正确性,对于不同材料的块体,只需结合其砌体轴压试验的峰值应力与应变,即可得到具体的本构关系表达式。
In order to establish a constitutive relation of masonry with parameter unified mode,the application of energy principle and the theory of damage mechanics explains the relationship between energy dissipation and damage energy in the process of uniaxial masonry compression and defines damage variable. A unified constitutive relation model with parameter is proposed by combining with a damage function and the stress-strain curve＇s characteristics under axial compression of masonry. The correctness of this model is verified by the test results of the perforated shale brick masonry which is under the axial compression. For the other material of masonry,the specific constitutive relation also can be defined as long as the peak stress and the strain of masonry under axial compression is obtained.
