Abstract: The decks of composite girders at the half of 1970's were designed too thin, so that many decks were unable to stand up to heavy traffic and damaged seriously. This type of girders were reduced to construct for a long time. For the reason of demand to reduce constructional costs, we must consider what kind of way of designing it is rational. But there are many inconvenient problems, because the design criteria have not been revised since 1973. The problems are caused by what the present design techniques of concrete construction are not incorporated into the design criteria. And the problems develop from the way to treat creep and shrinkage. Also, the crack of surface and inside causes problems when we are examined about the durability and the safety of the concrete structure. In this paper, we did the research that it paid attention to creep and shrinkage shown as the factor of the crack occurrence. So, we applied the finite element method to reinfoced concrete deck of composite girders, and we made an analytic program, and we analyzed the resultant stress and displacement.
