1st Edition
Analysis and Design of Gravity Flow Conduits and Buried Bridges
This book encapsulates the analysis and design of buried gravity flow conduits, including pipe materials and soil materials and their interaction. These range from traditional pipes to open bottom concrete and corrugated metal culverts with spans of up to 25 metres, and include culverts, storm drains, sewers, and buried bridges.
It begins with historical background and easily understandable design models then considers the properties of pipe materials and of pipe rings and backfill soils and the commonalities in their behavior. Finally, design methods consider the interaction of pipe and soil, along with simplified and computer methods. Much of this has been adopted by the AASHTO Committee on Bridges (responsible for highway culvert design) and other standards.
The book will be important to any practicing engineer working on buried pipe design, including public engineers at all levels, private consultants, and product manufacturers, and will also suit researchers as a unified and comprehensive presentation.
Introduction. Culvert Behavior as Seen Through the Eyes of Early Research. Culvert Materials and General Conduit Behavior. Soils and Soil Models. Soil-Conduit Interaction. Finite Element Modeling.

Biography
Tim McGrath spent almost 40 years with Simpson Gumpertz & Heger Inc. Before becoming Principal with TJMcGrath, LLC. Most of his career has been involved in research, design and investigation of gravity flow pipes and culverts. He is past Chair the AWWA Committee on fiberglass pipe and the TRB Committee on Culverts and Hydraulic Structures. He often advises the AASHTO Committee on Culverts on proposed modifications to material and design standards.
Ian Moore is Canada Research Chair in Infrastructure Engineering at Queen’s University, Canada and Editor of the Canadian Geotechnical Journal. He is founder and director of the GeoEngineering Laboratory at Queen’s University – North America’s (and likely the world’s) most active and influential laboratory specializing in buried pipe infrastructure.
