Abstract:
Aiming at the rigidity identification of bridge, based on general bridge loading test, a step-forward loading method was proposed for bridge rigidity quantitative identification. Rigidity effect factor matrix was introduced, measured deflection variation matrix and calculated deflection variation matrix were established by step-forward loading and finite element model respectively, then the deviation was controlled to get convergence to identify rigidity effect factor, and related analysis flow was illustrated. Based on a project of tie-arch bridge, the identification accuracies of single zone damage and multi-zone damage of bridge were verified. Test result shows that the accuracy of bridge identification is 6.6% except the zones near arch feet. The rigidity of concrete bridge can be located and quantitatively identified based on step-forward loading method. Using polynomial fitting to correct the measured data can improve the identification accuracy, and the convergence level increases by 18%. 8 figs, 20 refs.
