In a method for designing a multi-step tension prestressed girder, prestress is appropriately introduced with respect to a relationship between a load and stress, for each step of construction, so that the height of a profile of the girder can be reduced. In a method for fabricating a multi-step tension prestressed girder, prestress is appropriately introduced with respect to a relationship between a load and stress, for each step of construction, so that the height of a profile of the girder can be reduced.
