| Abstract: | Stres, strain and deflection datas, were tested in the destructive experiment. The relationship between the de- flection, crack variations and the unloading load were also made in the specimens, prestressed slab beams in the Beidaihe highway bridge over the Jingshan railway. It was finally decided if the beams were valuable based on the research and some data was advised for the reforcement plan. |
