Nine model concrete spheres reinforced with steel liners located on the inside, outside, or both inside and outside were tested to failure under hydrostatic loading. The quantity of reinforcement varied from 1.8 to 23.9 by area for this range of reinforcement, the spheres showed increases in failure pressure from 0 to 374 over that of unreinforced concrete spheres 2,810 psi. Using a nominal 12 reinforcement, it was found that the best reinforcing method was to place liners on both the inside and outside of the wall. Author
