Abstract:

Two research efforts supervised by the author of this paper and the significance of the findings of those research projects are used to facilitate the discussion to explain a couple of the challenges that the structural engineers faced in the recent past. These research programs are (i) development of the new Strut-and-Tie design provisions of AASHTO LRFD Bridge Design Specifications, and (ii) development of a new prestress loss calculation procedure.

This paper was prepared with the aim of contributing to a session organized to honor Professor Michael Collins of the University of Toronto. The discussion provided within this paper is founded on the teachings of Professor Michael P. Collins and on the experiences of the author as a graduate student. More specifically, the author of the paper had the privilege to learn from Professor Collins (i) the importance of accuracy in calibrating design provisions and (ii) the significance of reducing the design expressions down to the essential parameters. Thus, the research projects summarized in this paper serve to present examples for those important concepts and are from the personal experiences of the author.
