Ultra-high performance concrete (UHPC) is a relatively new class of cementitious material that utilizes fine particle packing and the inclusion of steel fibers to achieve high mechanical and durability properties. Although UHPC is superior to conventional concrete in regards to almost all physical properties, its structural usage is still somewhat limited, particularly in the US. Most of the current uses of UHPC are highly specialized, such as bridge deck overlays and bridge deck longitudinal joints. However, the enhanced properties of UHPC, particularly its uncharacteristically high tensile strength, make it very suitable for implementation in long-span structural elements. While research has been underway for the better part of two decades to implement this material in such structural elements, this prior research has been focused almost primarily on transportation structural elements. The research herein aims to apply the existing knowledge of the structural behavior of UHPC to building structural elements. The primary objective of the current work is to develop rational design guidelines for the implementation of UHPC structural elements. The current lack of such guidelines in the United States has been prohibitive to widespread adoption of UHPC. Specifically, the research presented in this thesis examined the feasibility of a 60 ft long by 60 ft wide floor system for typical buildings, composed strictly of UHPC beams and girders. This research encompassed a variety of structural testing performed on cross-sections to be economical and safe for their intended uses. As each specimen was rather unique, testing targeted the most critical failure modes. Upon completion of structural testing, the results were analyzed and compared to existing or proposed design equations, as well as to expected in-use demands.
