concrete pipe crushing strength

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 crack

Structural Design Condron Concrete

The required crushing strength of a concrete pipe can be calculated using the following equation. Wt > (We x Fs) / Fm. Where: Wt = required I.S.6 crushing load (kn/m), (Fn=Wt) We = Total applied load on the pipe (kn/m) Fs = Factor of safety (1.25 MINIMUM) Fm = the bedding factor. Crushing load (Wt) as stated in I.S. 6: 2004 “Perforated Pipes” Table
