| Abstract: | Aiming at the problem of choosing reasonable value of attribution parameters of pre-stressed curved bridge,the method of attrition loss test of pre-stressed wire is introduced,with the combination of the test of attrition loss of pre-stressed wire of curved bridge and finite element model analysis.The relation between curvature radius and attrition loss is analyzed,and the advice to choose the value of attrition factors is proposed,which serves as a reference to calculate attrition loss of the same type of ... |
