Shells: Intersecting cylinders
|
Image-GoddenE71 Terminal Building, Lambert Field Airport. Constructed from modules consisting of four intersecting concrete cylindrical shells which form a 120 ft square with 15 ft overhang in the center of each shell (hence forming an 8 sided figure in plan). The height at the center is 32 ft. Slide taken in 1962 when three modules had been constructed. (St. Louis, Missouri) | |

Image-GoddenE72 Terminal Building, Lambert Field Airport. Taken in 1980 after the construction of additional shell modules. The shells are 4 1/2 in. thick increasing to 8 in. at the diagonal and perimeter stiffening ribs which are supported at ground level on fixed hinged bearings. The bearings use 8 in. diameter steel pins. Bearings are tied together at floor level with 8 in. X 1 in. steel ties on the perimeter (not on diagonal as in the structure of GoddenE46).
