| Abstract | Ultra-high performance concrete (UHPC) is an advanced cementitious composite material which has been developed in recent decades. When compared to more conventional cement-based concrete materials, UHPC tends to exhibit superior properties such as increased durability, strength, and long-term stability. This experimental investigation focused on the further development and structural testing of a newly developed highway bridge girder cross section, namely the pi-girder. This girder was developed and optimized specifically to exploit the advanced mechanical and durability properties of UHPC. Structural testing was completed on full-scale girders to investigate the transverse flexural response and the longitudinal joint structural behavior. The 2nd generation pi-girder system surpassed the AASHTO LRFD Bridge Design Specification demands for which it was designed. |
