Concrete Pipe Design - CivilWeb Spreadsheets

Concrete Pipe Crushing Strength In the UK the minimum crushing load is usually specified as a multiple of the nominal pipe diameter. The most commonly specified strength class is 120, so the crushing strength in kN/m will be 120 times the nominal pipe

Recommendations for Design of Reinforced Concrete Pipe ...

The required strength of the concrete pipe is determined from the effects of the bending moment, thrust, and shear in the pipe wall.
