Structural Concrete
Strut-and-Tie Models for Unified Design

Dr. S. E. Metwally has broad experience in the structural design of many municipal and industrial structures, bridges, and large-scale roof structures. His academic positions in Egypt include Head of the Structural Engineering Department at El-Mansoura University and Tanta University, Professor of Concrete Structures at El-Mansoura University, Alexander von Humboldt fellow at the Institute of Structural Design, University of Stuttgart, and Visiting Professor at the University of Hawaii at Manoa. Dr. Metwally obtained his Ph.D. from Purdue University, and his M.S. from George Washington University. Honors include the State Prize in Structural Engineering and the Encouraging State Prize in Engineering Science both granted by the Egyptian Academy of Science and Technology, and the award of Distinction of First Class granted by the President of Egypt.

Dr. Wai-Fah Chen is a well-respected leader in the field of plasticity, structural stability, and structural steel design over the past half-century. He has made major contributions introducing the mathematical theory of plasticity to civil engineering practice, especially in the application of limit analysis methods to the geotechnical engineering field. Having headed the engineering departments at the University of Hawaii and Purdue University, Dr. Chen is a widely-cited author and the recipient of several national engineering awards, including the 1990 Shortridge Hardesty Award from the American Society of Civil Engineers and the 2003 Lifetime Achievement Award from the American Institute of Steel Construction. He received his Ph.D. from Brown University, and is Member of U.S. National Academy of Engineering and Member of Taiwan’s National Academy of Science (Academia Sinica), formerly Distinguished Professor of Civil Engineering at Purdue University and Dean of Engineering at University of Hawaii. He is currently a Research Professor of Civil Engineering at UH.
