Summary

Expertise and Current Research Activity

I am a structural engineer with a strong interest in materials. My research emphasizes three main areas. Two involve lengthening the service life and improving the cost effectiveness of highway structures with major emphasis on bridges, and the third involves improving the bond strength of reinforcing steel to concrete.

All three areas are of prime importance to the nation. For example, it is estimated that the annual cost to eliminate bridge deficiencies over the next twenty years will exceed $10 billion. It is further estimated that the cost to users due to traffic delays and lost productivity is ten times this value. Ninety percent of the cost of bridge deficiencies is due to corrosion. To address these problems, my research involves evaluating and developing corrosion protection systems for reinforcing steel and developing design and construction techniques to improve the life of bridge decks. In the field of bond, my research addresses the development of design criteria for anchoring high-strength reinforcing steel to concrete, an area that is now drawing world-wide attention because of its potential to significantly reduce material and construction costs.

Why Study at the University of Kansas?

KU is one of the top research universities, internationally, in all three fields.
