| Abstract: | In order to study the shear lag effect in practical engineering application, the three-bar simulation method is used to calculate the shear lag coefficient of a single cable plane concrete box girder cable-stayed bridge during construction stage, which is based on the idea of the three bar simulation method, and then the calculations are compared with the measured data to finger out that the three bar simulation method in construction stage can meet the engineering requirements. |
