Abstract
A wall and roof structure primarily for buildings that are partly under ground. In the roof structure, sheets of steel are placed in an upward concave position supported by beams and columns with compression members positioned between the beams. In the walls, a similar arrangement is used with sheets of steel in a concave outward position supported between the columns. This provides a free span suspension design with no columns or bearing walls needed inside the basic structure.
