Since using of Cellular and Castellated Beams can provide higher bending strength and stiffness without increasing the weight of the structure, therefore, in the recent years, they have lionized by most of researchers. In some of structures like bridges, in order to large stiffness and high strength, we have to use special beams with large dimensions and height. On the other hand, to solve this necessity, it is not possible to use hot-rolled Castellated Beams. So Castellated plate girders can be used. In this paper, it is denoted that castellated plate girders can be used in long spans as a convenient choice.
