Design of Reinforced Concrete Deep Beams for Strength and Serviceability (2009)

Abstract Several reinforced concrete bent caps (deep beams) in Texas have developed significant diagonal cracks in service. The cracking in two bent caps was so extensive that costly retrofits were implemented to strengthen the structures. Strut-and-tie modeling is currently recommended … Continue reading

Design and Construction of Small-Scale Bridge Bents on Drilled Shaft Foundations (2005)

Abstract The response of structures with deep foundations subjected to dynamic loading is of key interest in areas of high seismicity and is not well understood. This lack of understanding has resulted in design practices which may be overly conservative … Continue reading

Survey of Costs, Economic Analysis, and Design Guidelines for Corrosion Protection Methods for Post-Tensioned Concrete Bridges (2005)

Abstract At the design stage, engineers and owners have the most influence on the future durability of post-tensioned concrete bridges. Yet design guidelines are not clear on what corrosion protection methods are appropriate for a given exposure environment. Current specifications … Continue reading

Design Provisions for Autoclaved Aerated Concrete (AAC) Infilled Steel Moment Frames (2009)

Abstract In this dissertation, the seismic behavior and design of AAC-infilled steel moment frames are investigated systematically. The fundamental vehicle for this investigation is the ATC-63 methodology, which is intended for the establishment of seismic design factors for structural systems. … Continue reading

Conclusions, Recommendations and Design Guidelines for Corrosion Protection of Post-Tensioned Bridges (2004)

Abstract The effectiveness of cement grout in galvanized or polyethylene ducts, the most widely used corrosion protection system for multistrand bonded post-tensioned concrete tendons, has been under debate due to several reported examples of significant tendon corrosion damage. While experience … Continue reading
