Abstract
A building structure including a beam of steel or rod reinforced concrete which is sheathed in a U-shaped cross section steel shell, a concrete column which is encased in a steel tube, diagonal bracings and connecting members thereof. The topside of the U-shaped steel shell is open to allow concrete to be filled therethrough. Steel rods are placed in the shell and a steel panel connecting member secures the opposed sidewalls of the shell. Steel bars extend from a floor slab into the beam shell through the aforesaid open topside, thereby rendering the beam integral with the slab. Frame-like steel members for confining reinforcing bars and/or shear connectors are disposed in the inside of the beam shell. A steel sleeve is also provided in the beam shell for defining a space for disposition of equipment. In addition, an opening is provided in the bottom wall of the beam shell so as to allow steel rods to extend from the wall into the beam shell, thereby rendering the beam integral with the wall. A column is coupled to the beam by means of ring stiffeners or gusset plates. Diagonal bracings are positioned in symmetric relation to the frame member of the beam or column, and the diagonal…
