摘要
综合分析了混凝土断裂特征 ,和描述载荷与变形关系曲线连续函数 根据混凝土断裂过程区的观测结果 ,推出以幂函数多项式表达断裂过程区虚拟裂纹张开位移的表达方法 ,通过最小二乘法导出了计算该多项式中待定系数的代数方程 。
The concrete fracture behaviors are analyzed,and a continuous function is proposed to describe the relationship between the loading and deformation for concrete fracture testing specimen.Based on the fracture experiment results of concrete,a method expressing the crack opening displacement in FPZ is presented by using power function series.The parameters of series function are determined through a group of algebra equation,and the algebra equations are produced by least square method.Many calculation examples from actual concrete fracture experiment and analysis discussion are also given.
