Large-Diameter Steel Water Pipe: Comparing Classic and Recent Design Procedures for External Earth Loads
Steel pipe has long been designed for internal pressure with varying safety factors applied to the allowable design stress in the steel cylinder. Earth loads on rigid pipe were first developed in 1913 by Anson Marston and then modified by Marston and Merlin Spangler in the early 1930s for flexible pipe. However, checking steel water pipes for resistance to external loads was not common until the early 1960s after Reynold Watkins corrected the original Iowa Formula (by Spangler) and the Modified Iowa Formula was published in 1958. This paper will discuss the use of the Modified Iowa Formula that is still utilized by many design engineers along with subsequent work that has been developed over the past 50 years and published. This subsequent work is based on measurable soil parameters that will be presented and discussed along with steel water pipe serviceability levels against external loads.
