基于材料的实际应力—应变关系,采用非线性分析方法,计算混凝土及石砌桥墩墩身截面弯矩增大系数.模型试验结果表明,本计算方法是合理可行的.
Based on the material’s actual stress-strain relationship, the nonlinear analysis method was used to calculate the coefficient of increase of moment of concrete cross-section of pier and concrete pier.The results of model test show that this method is reasonable and feasible.
