Load Carrying Capacity Analysis of Continuous Girder Bridge Based on Load Test

In order to accurately assess the load carrying capacity and actual working condition of a newly constructed continuous girder bridge, the load test of a newly constructed three-span prestressed variable cross-section continuous girder bridge is taken as the engineering background, and the check coefficient of the static load test, relative residuals and other parameters are used to judge whether the indexes such as the strength and stiffness of the structure satisfy the requirements or not. The results show that the deflection and strain calibration coefficients are less than 1 and the relative residual value is not more than 20% when the loading efficiency is between 0.85 and 1.05, indicating that there is surplus of structural stiffness and the deformation can be recovered after unloading, and the structure is in an elastic working state.
