| Abstract: |
The dynamic response depends on the bridge span, stiffness and surface roughness, and vehicle dynamic characteristics. Unlike earthquake loads which can cause vibration in bridge longitudinal, transverse, and vertical directions, moving vehicles mainly excite vertical vibration of the bridge. The highway bridges have been constructed a lot in Vietnam recently. These bridges have been designed with AASHTO LRFD and moving truck load is HL93 loading. However, the vehicles are actually different with HL93 loading. Moving loads caused the impact effects, the changing of frequencies of bridge structure. The heavy vehicles were considered in this study. The impact effect of the highway bridge due to the actual heavy vehicle is investigated and evaluated. Comparison of results from both computations of dynamic analysis and loading test are shown in the paper. |
