Abstract:

To explore the application of hammer system in bridge dynamic test， simply supported bridge with standard span were selected. Research on dynamic load allowance （DLA） test of simply supported bridge were carried out， adopting theoretical derivation， numerical simulation and experimental verification. Firstly， the vehicle-bridge-suspension system coupled vibration theoretical equation was derived according to d'Alembert principle. Then， the analysis program was compiled based on ANSYS to obtain the DLAs of suspension hammer method. The influence of suspension length， wire diameter， elastic modulus and suspension hammer mass on the accuracy of DLA were discussed， comparing with the results of scaffolding method. Furthermore， combining with response surface methodology， the suggested value of suspension hammer system parameters about different bridges types were proposed. Finally， a 30 m simply supported box girder bridge was tested under dynamic load. Dynamic deflection of the bridge was tested by scaffolding and suspension hammer method to verify the suggested value. Results demonstrated that there is a significant interaction between wire diameter and suspension hammer mass. To satisfy the difference of less than 5% between deflection DLA measured by suspension hammer and scaffolding method， the optimal values of wire diameter and suspension hammer mass should increase with wire length.

Key words: bridge engineering, simply supported girder bridge, dynamic load allowance, dynamic deflection, suspension hammer system
