General Information:. Erratum to M11, 5th Edition. The 5th Edition of AWWA M11 has been out since and the benefits to engineers have been recognized for the additional value it has created for steel pipe design. There were numerous changes and additions that are intended to clarify important criteria and procedures when designing steel water pipe.

The nature of engineering design is that the knowledge used to design large facilities is learned and remembered mostly during the work on a project. Steel pipe systems have been designed, fabricated, and installed with decades of experience, achieving reliable and long-lasting operational service, while establishing proven safety factors that the engineering community has trusted.

Steel pipe manufactured to AWWA standards are usually considered an engineered product and require a certain amount of engineering input to be functional for a water facility.

This article will review buried pipe deflection and corresponding safety factors. Buried Steel Pipe Deflection Design. Spangler for flexible pipe, and the Iowa formula were developed to predict how much load a flexible steel culvert could take without collapsing.

After developing the formula, Spangler ran into problem making the formula work properly. Finally, one of his graduate students, Reynold Watkins, solved the problem and the Modified Iowa Formula was the result. It has been used in its original form since first developed in and has proven to be relatively accurate and conservative. The basic formula to predict steel pipe deflection as listed in AWWA M11 5 th edition is shown below. The terms represent the stiffness of the cement mortar lining and or cement mortar coating.

Good Engineering and The Deflection Formula. There are many variables in a buried pipe installation. They are reflected in the above deflection formula. The remainder of the paper will define the terms in the formula. Some are well defined and others require engineering decisions based on the conditions the pipe will be laid in.
