ABSTRACT:
A reinforced structure for resisting deflection of a tank wall that is subjected to a range of positive and negative pressures within the tank characterized by a plurality of closely spaced braced members disposed in general alignment and mounted on the tank wall so that upon limited deflection of the wall the brace members move into contact and thereby increase wall resistance to additional damaging deflection.
