Summary:

This document is a technical summary of the unpublished Federal Highway Administration report, Structural Behavior of a Prototype Ultra High Performance Concrete Pi Girder, available only through the National Technical Information Service (NTIS). NTIS Accession No. of the report covered in this TechBrief: PB2009 115495. This TechBrief highlights the results of a research program that evaluated an ultra high performance concrete (UHPC) pi girder cross section prototype developed for use in short and medium span highway bridge applications. UHPC is an advanced cementitious composite material which has been developed in recent decades. When compared to more conventional concrete materials, UHPC tends to exhibit superior properties such as exceptional durability, high compressive strength, usable tensile strength, and long term stability. This experimental investigation focused on the structural behavior of a newly developed highway bridge girder cross section, the pi girder. This girder was developed and optimized to exploit the advanced mechanical and durability properties of UHPC. Structural testing was completed on girders to investigate their flexural response, shear response, transverse flexural response, and lateral load distribution capabilities. Through this work, topics related to the design and fabrication of the pi girder were also addressed.
