Abstract:
The dissertation introduces some analyzing results of vertical displacement dynamic coefficient, rotational displacement, bending moment and shear force in structural part of design for Bong Son bridge in Binh Dinh province due to mobile load by numerical methods. The structure of Bong Son Bridge consisting of nine spans of section I girder with continuous beams. The vehicle live load of KAMAZ-55111 has three-axle moving on the bridge with different speeds. The study results show that the vehicle speeds are extremely influenced to the moving of continuous beam bridge I-section. Therefore, nowadays the use of common a dynamic coefficient in the bridge design process also needs to be noted more . The study results are the references to help engineers gaining more information in analyzing the safety bridge d
