Cracks found in structural elements have various causes. In concrete structures, it could be the opening of dry-joints between precast elements, in particular in those segmental-constructed box-girder bridges assembled with dry joints that are favoured in tropical countries. Dimarogonas[1] presented the state-of-art review of various methods in tackling the cracked-structure problem. Recently, Shifrin and Ruotolo[2] developed a method that can be used to tackle a beam with multiple cracks. However, their studies were limited to Euler beams.
