  • Method of manufacture of a concrete-filled steel bearing wall
    Patent number: 5653082
    Abstract: Disclosed is a concrete-filled steel bearing earthquake resistant wall which shows combined resistance to shearing forces exerted in the surface plane of an earthquake resistant wall. The wall comprises connecting members 1, a pair of surface steel plates 2 and 2' which are arranged in a parallel relationship to each other and secured by the connecting members 1 so that each space between these surface steel plates 2 is filled with the wall unit concrete 7, and wall unit periphery binding steel reinforcements 8 constructed from inverted U-shaped steel bars or similar material and arranged along the peripheral part of the wall unit concrete 7 at predetermined intervals so as to be fixed to said concrete 7. In addition, the slippage preventing members 6 are arranged in a staggered arrangement on the aforementioned surface steel plates 2 and 2'.
