Abstract : An experimental program involving construction and testing or reduced-scale concrete Horizontal MX-Missile Shelters was conducted. This paper describes the construction of 43 reduced-scale cement models of the Shelters. Twenty-two different prototypes were constructed. All specimens had a 2-ft (0.61 M) inside diameter with plain or reinforced concrete walls 1.8 (46 mm) or 2.4-in. (61 mm) thick. Specimen test length was 4 ft (1.22 m) with 1 ft (0.30 m) at each end for load transfer. Variables in specimen construction included wall thickness, amount of reinforcing, breakout joints details, liner thickness, spacing of studs, and Z-insert gap of the SAL inspection panel. Sensitivity of test results to variations in specimen dimensions required unusually rigid tolerances. In spite of manufacturing complexities, specimens were manufactured at a rate of three per week.
