Research Interests
Primary research areas involve the experimental investigation of reinforced and prestressed concrete structural systems subjected to earthquake or fatigue loadings. Interests include the design/detailing/ behavior of connections between precast elements, participation of the floor slab/panel systems in resisting lateral loads, bond strength and durability of reinforcement in concrete, evaluation and repair of damaged structures, and applications of high-strength concrete to the prestressed industry. Projects currently under investigation include the testing of connection components to be incorporated in multi-bay frame superassemblages subjected to cyclic lateral loads. In addition, an extensive materials research project is underway to investigate the effect of materials, curing, age, and test conditions on the behavior of high-strength concretes with compressive strengths in excess of 15,000 psi. Two full-scale high-strength prestressed bridge girders are to be subjected to fatigue, flexure, and shear tests.
