  • Structural Design Calculator Concrete Pipes BPDA

    Test strength of pipe (F n): The Structural design calculator test strength of a concrete pipe may be referred to as F c or F n Values are specified in BS 5911:2010. For a reinforced concrete pipe F c is the load which the pipe will sustain without developing a crack exceeding 0.30mm in width over a length of 300mm and F n is the load which the pipe will sustain without collapse, irrespective of

  • Recommendations for Design of Reinforced Concrete Pipe

    According to the direct design method, as in the indirect design method, the required supporting strength of the pipe is a function of the magnitude of earth pressure above the pipe and the pressure distribution around the pipe. The required strength of the concrete pipe is determined from the effects of the bending moment, thrust, and shear in the pipe wall. Wall thickness, concrete strength, and

  • Structural Design of Clay Pipes CPDA

    When a line of flexibily jointed pipes is bedded, haunched or surrounded in concrete, flexibility can be maintained along its length by employing 18mm thick compressible boards at pipe joints. These should extend the full height and width of the concrete and should occur at maximum intervals of 5m along the length of the pipeline. The boards should be positioned against the upstream end of pipe sockets or
