Abstract
A composite steel I-beam member. The member includes confined top and bottom flanges, and a composite laminated web. The confined flange comprises a wooden core and a metal jacket wrapped around an outer perimeter of the wooden core. The overall load carrying capacity of the composite I-beam is significantly increased through a list of composite actions occurring in the individual components and their connections. Most importantly, a two-way lateral interaction can be normal to the interface between the metal jacket and the wooden core and provide an amount of compressive support to the top flange surpassing the sum of amount of support provided by the metal jacket and the wooden core when being used separately.
