| 摘 要： | 运用Lem aitre损伤规律对土木工程中使用的混凝土圆截面桩受压弯荷载下进行损伤分析,推导了无量纲轴向力和无量纲弯矩的表达式,计算了不同失效应变对应的弯矩规律,以及不同失效应变和中性轴的无量纲位移之间的关系。分析结果可作为估算实际工程中混凝土圆截面桩抗弯承载力的参考依据。

| Abstract: | Lemaitre damage principle is used to analyze the damage of circular cross-section concrete pile under pressure and bending load in civil engineering and to deduce dimensionless axial force and bending moment expressions.Moment rules under corresponding failure strains are calculated and the relationships between neutral axis' dimensionless displacements and different failure strains are also calculated.The results can be used as references when calculating circular-section concrete pile's bending bearing ca... |
