ASCE has honored the writing team of Amir W. Botros; Gary J. Klein, P.E., M.ASCE; Gregory W. Lucier, Ph.D.; Sami H. Rizkalla, Ph.D., P.E., F.ASCE; and Paul Zia, Ph.D., P.E., Dist.M.ASCE, NAE, with this year’s T.Y. Lin Award for the paper “Dapped Ends of Prestressed Concrete Thin-Stemmed Members: Part 1, Experimental Testing and Behavior,” published in PCI Journal, March-April 2017.

This paper describes the behavior of dapped ends of prestressed concrete thin-stemmed members based on an extensive experimental program conducted to identify the most effective reinforcement schemes and develop design guidelines for dapped ends. Experimental research findings presented in this paper were used to develop the guidelines presented in a subsequent (companion) paper, “Dapped Ends of Prestressed Concrete Thin-Stemmed Members: Part 2, Design,” which also appears in the March-April issue of PCI Journal.

The experimental results indicated that the extent of cracking at service load, the ultimate strength, and the failure mode are influenced by the reinforcement arrangement at the dapped end.

The T.Y. Lin Award recognizes contributions to the field of prestressed concrete.
