本文从能量的观点分析了混凝土Ⅰ型和Ⅱ型断裂能表达式,探讨了梁自重对Ⅰ型断裂能的影响;介绍了Ⅰ型断裂能的测试方法,给出了拉应变软化曲线.
In this paper, the expressions of type I and type II fracture energy of concrete are analyzed from the viewpoint of energy. The influence of beam self-weight on type I fracture energy is discussed. The test method of type I fracture energy is introduced and the tensile strain softening curve is given.
