• Abstract:
  Research presented herein describes an application of a newly developed material called Ultra-High Performance Concrete (UHPC) to a ; single-span bridge. The two primary objectives of this research were to develop a shear design procedure for possible code adoption ; and to provide a performance evaluation to ensure the viability of the first UHPC bridge in the United States. Two other secondary ; objectives included defining of material properties and understanding of flexural behavior of a UHPC bridge girder. In order to obtain ; information in these areas, several tests were carried out including material testing, large-scale laboratory flexure testing, large-scale ; laboratory shear testing, large-scale laboratory flexure-shear testing, small-scale laboratory shear testing, and field testing of a UHPC ; bridge. ; Experimental and analytical results of the described tests are presented. Analytical models to understand the flexure and shear behavior ; of UHPC members were developed using iterative computer based procedures. Previous research is referenced explaining a simplified ; flexural design procedure and a simplified pure shear design procedure. This work describes a shear design procedure based on the ; Modified Compression Field Theory (MCFT) which can be used in the design of UHPC members. Conclusions are provided regarding ; the viability of the UHPC bridge and recommendations are made for future research.
