“Conception to Construction and Beyond: Design and Implementation of Prestressed Bridge Girders Using Locally Developed Ultra-High Performance Concrete”
Abstract: An emerging structural technology, ultra-high performance concrete (UHPC) exhibits superior strength and durability properties in comparison to traditional concretes, providing significant advantages to structural bridge design. Over the past decade, research in the Department of Civil Engineering at New Mexico State University has led to the development of UHPC mixture proportions consisting primarily of materials local to New Mexico and typical of precast/prestressed concrete production. Recent research has aided in the development of preliminary UHPC design provisions for the New Mexico Department of Transportation (NMDOT), and culminated in the redesign and reconstruction of a structurally deficient local bridge. A two-span structure, the new design includes prestressed bridge girders and provides one span using high performance concrete (HPC) common in New Mexico bridge design, while the second span implements the unique UHPC developed at NMSU. Both spans have been instrumented with various structural monitoring technologies, providing the unique opportunity for long-term investigation and direct comparison of the durability and performance of HPC and locally developed UHPC. This presentation focuses on the preliminary design and laboratory testing of full-scale trial girders, and highlights the many phases of the project including production of the girders, reconstruction of the bridge, and installation of bridge sensor.
Bio: Mark Manning is a second-year doctoral student in the Department Civil Engineering at New Mexico State University (NMSU), having received a BS and MS from NMSU in 2013 and 2015, respectively. His research focuses on ultra-high performance concrete (UHPC) developed using primarily local materials, specifically the design, production, and testing of precast/prestressed bridge girders. The objective of these investigations is to provide experimental, analytical and numerical evidence for the development of design tools and recommendations for the incorporation of UHPC in local bridge design.
