Concrete Pipe & Pipe Design

Location:  Frisco 1

Speakers:  Trevis Hanson, C.E.T. – Canada Concrete Pipe & Precast Association

Presentation Description
Concrete pipes are the backbone of our precast industry. Concrete Pipe and Pipe Design presentation starts with a walk thru the early years of the use of concrete by the Romans and shows the evolution towards the multiple applications that use concrete pipes nowadays. Then I bring people back to the basics and explain what is precast concrete and the 2 concrete types used to manufacture concrete pipes, concrete properties, and standards.

Now that the basic knowledge is established, I move to the basis of concrete pipes: terminology, design basic concepts, comparison of the behaviour of rigid pipe vs a flexible pipe underground, the difference in the installation standards for both pipes, and then I highlight the 2 design methodologies for the concrete pipe which takes me to explain the 3EB-test and the reinforcement placement and manufacturing.

Then, the presentation moves to the design part: I explain the 5 basic steps to design a concrete pipe using the indirect design method and I do a live demo of a design in pipepac.

Lastly, a brief mention cracks and crack assessment.
