ABSTRACT
A 2.7 m high conical plate roof, constructed of 5 mm welded stainless steel plate segments had been assembled at ground level, next to the tank wall and foundation. The roof structure was reinforced by eighteen, radially oriented, W10× 17 beammembers, on a 20 degrees circumferential spacing. The outer edge of the roof assembly included a circumferential 13mm× 152mm× 203mm compression angle, with the 8′′ leg extended outward in the radial direction.
