Concrete Pipe Design - CivilWeb Spreadsheets

The structural capacity of the concrete pipe and bedding system can now be calculated simply as the concrete pipe crushing strength multiplied by the bedding factor divided by the factor of safety. This capacity is now simply checked against the total of the loads acting on the pipe to determine if the pipe and bedding system proposed is adequate.

Concrete Pipe Precast - County Materials

Concrete pipe and precast products must efficiently convey the fluid for which they are designed. Secondly, they are structures, and must be able to support the weight of the earth, as well as live loads above it. Unlike alternate products, concrete pipe accomplishes both functions through its inherent strength and rigidity.
