| Abstract: | Some factors that induce cracking of concrete curved girder bridges are discussed, such as temperature, pre-stressing, shrinkage and creep of concrete, location of bearing, design and calculation, construction method, etc. Several recommendations from design and calculation, construction and strengthening are proposed to resist cracking of concrete curved girder bridges. |
