### Concrete Drainage Pipes - Marshalls CPM

Circular concrete pipes are all manufactured to strength class 120 (minimum crushing load for a particular size of pipe is equal to 120 multiplied by DN of pipe divided by 1000).

### Recommendations for Design of Reinforced …

The bedding factor is defined as the ratio of the supporting strength of pipe under the field loading condition (W) to the supporting strength of similar pipe in a TEB test. Because cracking in concrete is a function of tensile stresses in the pipe wall, it can be shown ( Spangler 1933 ; ACPA 1991 ) that the bedding factor can also be expressed as a ratio of moments in the TEB test and field conditions.
