| Abstract: | In the light of the main reasons causing early cracks of a batch of 13m pre-cast reinforced concrete hollow slab members of four certain bridges, the possibility of the occurrence of cracks is discussed in detail and the influences of the early cracks on structural behavior of bridge slabs are shown by numerical analysis. Effective and valuable anti-cracking measures and technical proposals are recommended from design, construction and amendment of design specifications. |
