Steel deck plate is a preferable structure in the long span bridge construction because of the weight decrease and the aesthetic enhancement. But its orthogonal anisotropic structure is connected with various subsidiary materials so that the fatigue transfer is complex. This study will be conducted with the a few strain gauge is installed in the weak range of hot spot stress where the actual fatigue crack is anticipated and will compare it with the fatigue crack range and the allowable fatigue stress category of the steel deck plate in home and abroad
