LABORATORY INVESTIGATION OF REINFORCED CONCRETE CULVERT PIPE

An analysis and description of tests made on 36 reinforced concrete culvert pipes varying in size from 24 in. to 84 in. in diameter and constructed in accordance with proposed specifications was presented. The purpose of the tests was to determine the acceptability of pipe manufactured and tested in accordance with the proposed specifications and to determine the strains in the concrete and reinforcement of this pipe. Full-size strength tests were made on 36 pipes and 36 concrete test cylinders using a 1,000,000-lb. testing machine. Tensile tests were made on samples of the reinforcing steel and absorption tests were conducted on pre-cast absorption specimens. Strains were measured at the vertical and horizontal diameters of the pipe and on the concrete test cylinders and the reinforcing bar samples. Among the conclusions are: 1) The pipes exceed the load requirements of the proposed specifications. 2) The ultimate load on the pipe was increased by an increase in concrete strength and by the additional reinforcement in the extra strength pipe. The concrete in the pipe at ultimate load usually failed by crushing or by shear after yielding of the steel took place. 3) In the larger size pipes there was a more complete interaction between the concrete and reinforcement tensile strains than in the smaller size pipes.
