| Abstract: | The effects of traffic overloads on the reinforced concrete slab bridge is studied in this paper.The structural responses including stresses and deflections are monitored as the particular vehicle passing the bridge.Also,the structural responses are calculated by theoretical analysis.By comparing the measured and analyzed responses,it is found that the linking strength between slabs is decreased under overloads.The bridge condition after the passing of the particular vehicle is rated according related specification. |
