YELLOW FORCES GOVERN THE DESIGN

Strong floor O

The test floor is a five cell reinforced concrete box girder 40 ft. (12.2m) long, 60 ft. (18.3m) wide, and 8 ft. (2.5m) overall in height. The thickness of the top test floor slab is 18 in. (46 cm). Tie down points consist of (4) 2 1/2" holes which are arranged symmetrically in both directions. Each tie down point has an axial load allowable capacity of 250 kips (1112kN).
Capacity Data
 Each tie down point has an axial load allowable capacity of 250 kips (1112kN).
