Available in PDF, EPUB and Kindle. Book excerpt: Research is presented herein describing the behavior of a newly developed material called Ultra-High Performance Concrete (UHPC). The two primary objectives of this research are to develop a shear design procedure for possible code adoption and to provide a performance evaluation of structural testing to ensure the viability of the first UHPC bridge design in the United States. Two other secondary objectives will be helpful in this pursuit including: defining of material properties and understanding of flexural behavior. In order to obtain information in these areas several tests have been 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. In addition future field testing will be completed on the UHPC bridge. Experimental and analytical results of the described tests are presented herein. Analytical models of flexure and shear behavior have been developed using iterative computer based procedures. Previous research has been 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 for UHPC. The main difference in the procedure for use with UHPC is the consideration of residual tensile strength of the concrete after cracking. Finally, conclusions are provided about the viability of the UHPC bridge and recommendations are made for future research.
