The Miracle that is Concrete


Shih-Ho (Simon) Chao, Ph.D., P.E.

Associate Professor of Civil Engineering
University of Texas at Arlington


Concrete - strong and durable, yet brittle and weak in tension. Structures built with concrete thousands of years ago can still be seen and used today. Also seen today is the Allen, Texas football stadium, constructed in 2012 but condemned just two years later because of severe cracking in its concrete. What factors contribute to concrete's strengths and weaknesses, and how are researchers developing concrete composites that have better cracking resistance capability, ultra-high compressive strength, and ductility?


In this presentation, Dr. Chao provides a brief history of concrete and reviews recent research developments - from shrinkage control fiber-reinforced concrete and high-performance fiber-reinforced concrete to the next-generation concrete known as ultra-high performance fiber-reinforced concrete that exhibits very high compressive strength (25-30 ksi) and tensile ductility.


Shih-Ho (Simon) Chao earned a B.S. in bioenvironmental system engineering from the National Taiwan University, an M.S. in structural engineering from the National Chung-Hsing University and a Ph.D. (specializing in structural and materials engineering) from the University of Michigan, Ann Arbor. His research interests include high-performance fiber reinforced concrete, prestressed concrete, steel structures, large scale structural testing, and seismic design of structures. Professor Chao is the author of Performance-based Plastic Design - Earthquake Resistant Steel Structures and the recipient of an Excellence in Structural Research award from the American Concrete Institute.
