Finite Element Modeling of Large Diameter Steel Pipes and the Real World
Large-diameter water pipes are integral parts of today’s modern cities and their continuous performance is essential to the resiliency of infrastructure. The increase in water demand due to the increasing population in growing cities makes the use of large-diameter pipes and fittings inevitable. However, there are still gaps in knowledge about the behavior and design of large diameter pipes that are not covered by current guidelines and manuals. This presentation will give insight to recent achievements by UTA to address some common issues related to soil-pipe interaction and large-diameter fittings. A well-accepted robust three-dimensional nonlinear finite element (FE) model of large diameter buried steel pipes with the ability to simulate backfill layer placement, compaction effects, consideration of soil-soil and soil-pipe interaction, and its effects on pipe stresses and deflections are presented.

Himan Hojat Jalali, Ph.D. is an Assistant Professor at the Civil Engineering Department of the University of Texas at Arlington (UTA). He has a Ph.D. in Structural and Earthquake Engineering from the Sharif University of Technology with a focus on the behavior of buried steel pipes subjected to differential ground movement caused by reverse faulting. At UTA he has taught fundamental undergraduate and graduate courses such as Mechanics of Material, Statics, Finite Element Analysis, Advanced Mechanics of Materials, and Structural Dynamics. His current research work includes design and analysis of buried infrastructure, service life estimation of buried infrastructure, and structural control. He is a committee member in UESI/ASCE TC on Seismic Design of Buried Water & Wastewater Pipelines, and also is a volunteer member of AWWA Engineering Modeling Applications Committee. He has given several invited presentations at international conferences and published his peer-reviewed research findings in top-ranking journals and conferences.
