Strength and Behavior of Thick Walled Reinforced Concrete Conduits.
Abstract
The results of tests of 8 three-opening reinforced concrete conduits designed for soil loadings of 30 k/square feet are presented and discussed. The test specimens were 3/8 scale models of prototype designs, and were constructed with conventional deformed bars and concrete with 1-in. aggregate. The clear span-depth ratios in critical members ranged from 2.5 to 5.6. External loads were applied in both vertical and horizontal directions simultaneously, so that significant thrusts were acting in all members in addition to the bending and shear forces. Failure loads ranged from 82.5 to 150 k/square feet vertical load for members with span-depth ratios of 4.0 or less. Horizontal loads of 60 to 75 k/square feet produced failures in members with span-depth ratios of 5.6. All members failed in shear.
