  • Weighted membrane structures
    Patent number: 5009041
    Abstract: Weights in the form of water-filled flexible tubes are attached onto the pressure supported roof membrane of a building. The weights contour the membrane from a single dome into smaller elongated domes. The decreased radii of curvature of the smaller domes substantially reduce both the stress within the membrane and tension exerted by the membrane on the building walls.
