Overview

Discover the essentials of structural steel design with Segui/Soleimani's industry-leading STEEL DESIGN, 7th Edition. This textbook stands out by focusing on the design of individual members and their connections, rather than the integrated design of buildings. Its unique approach offers the flexibility to teach either LRFD (Load and Resistance Factor Design), ASD (Allowable Stress Design) or both, depending on your schedule. The text also includes both includes both SI and US Customary units and empowers your students to apply fundamental design principles through practical procedures, while reinforcing a strong theoretical foundation. This best-seller is perfect for junior and senior engineering students, with advanced chapters suitable for graduate-level courses. Practicing engineers will also find it a valuable reference for staying updated with current standards.

William T. Segui

William T. Segui is a Professor Emeritus of Civil Engineering at The University of Memphis, where he has been a member of the faculty since 1968. He holds a B.S.C.E, M.S., and Ph.D. from the University of South Carolina. After obtaining his B.S.C.E., he served as a commissioned officer in the U.S. Air Force. He then joined Wilbur Smith Associates, where he was a highway bridge designer. During graduate school, he received an NSF Graduate Traineeship. Since joining the Department of Civil Engineering at The University of Memphis, he has received two NASA/ASEE Summer Faculty Fellowships at the Marshall Space Flight Center in Huntsville, Alabama. Dr. Segui has worked several summers for various consulting firms and for the U.S. Army Corps of Engineers. He received the University of Memphis Distinguished Teaching Award in 2000. Dr. Segui is an emeritus member of the American Institute of Steel Construction and is a member of the Committee on Manuals. He received the 2011 AISC Special Achievement Award for his contributions to steel design education. He is a Life Member of the American Society of Civil Engineers and a member of the Tennessee Structural Engineers Association. Dr. Segui is also a licensed professional engineer in Tennessee.

Sayed Soleimani

Sayed Mohamad Soleimani currently serves as Professor of Engineering Practice within the Lyles School of Civil and Construction Engineering at Purdue University. His academic journey includes earning a B.S.C. in Civil Engineering from Sharif University of Technology in Tehran, Iran, followed by achieving both an M.A.Sc. and a Ph.D. from the University of British Columbia in Vancouver, Canada. Before assuming his position at Purdue University in 2024, Professor Soleimani made notable contributions in academic and industrial settings. He was a Teaching Professor at Penn State University for two years and held the position of Associate Professor and Department Head at the Australian University in Kuwait for nine years. Professor Soleimani boasts over 15 years of rich industrial experience, specializing in bridge engineering, concrete and steel design and construction and project management. His professional credentials include licensure as a professional engineer in California, British Columbia, Ontario and Australia. He has also been honored as a Fellow of the Institution of Engineers Australia.

FLEXIBLE APPROACH OFFERS YOU THE OPTION TO TEACH LRFD OR ASD: This book is designed so that you can easily teach either LRFD (Load and Resistance Factor Design), ASD (Allowable Stress Design) or both approaches. This edition does emphasize LRFD as the most recent and applicable of the two approaches, however, most examples incorporate both LRFD and ASD solutions.
END-OF-CHAPTER PROBLEMS PROVIDE HANDS-ON LRFD OR ASD PRACTICE WITH ANSWER KEYS: When appropriate, the required approach is specified within the statement of the problem. Plus, for your convenience, answers are provided within the book for key problems so readers can easily check their comprehension.
BLENDS MEANINGFUL PRACTICE WITH AN EMPHASIS ON THEORY: Although this book is oriented toward practical design, the authors present the supporting theory to ensure students have the complete understanding necessary for engineering success.
