Abstract
The 2000 interim version of the AASHTO LRFD Bridge Design Specifications has extended the applicability of the provisions for the design of composite plate girders in positive bending to include 70 ksi High Performance Steel. The change made in the 2000 interim code is based on analytical work. This thesis provides a summary of experimental work, which was conducted with the purpose of verifying the safety of the implemented changes in the 2000 interim code. The results of the two tests conducted indicate that, although being slightly over conservative, the code's current strength predictive equation, with the inclusion of 70 ksi High Performance Steel, is adequate. It was also observed that the tension flange of composite flexural members constructed using HPS-70W steel could achieve large levels of tensile strains without fracture.
