| 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 structural behavior 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 girders and sections of girders so as to investigate the flexural response, the shear response, the transverse flexural response, and the lateral load distribution capabilities of the girder. The knowledge gained through this study present a path forward to a viable structurally-optimized UHPC bridge superstructure system. Further development of the pigirder system is underway. |
