Meeting and Technical Seminar:

“Traditional and Advanced Methods for Assessing Ponding Instability”

Mark D. Denavit, Ph.D., P.E., University of Tennessee

The accumulation of water on roofs can cause progressively increasing deformations and even collapse. This effect, known as ponding, is a design consideration for all buildings. The most commonly used method of assessing roofs for ponding was developed over 50 years ago and has many limitations. A new method of design has recently been developed which more accurately captures the behavior of roofs under ponding conditions through computer analysis. This presentation will review ponding requirements in current specifications for design, introduce the new method of analysis, and compare the traditional and advanced methods through a range of examples.


Mark Denavit is an assistant professor at the University of Tennessee, Knoxville. He obtained his doctoral degree from the University of Illinois at Urbana-Champaign and previously worked as a design engineer at Stanley D. Lindsey and Associates, Ltd. in Atlanta, Georgia. He is a member of the AISC Committee on Specifications, Task Committee 5 on Composite Design, associate member of the SEI ASCE 7-22 Snow and Rain Loads Subcommittee, chair of the SEI/ACI Composite Construction Committee, and a professional engineer in the state of Georgia.
