Hannah and Nathan are both Graduates from the University of Alabama, where they each obtained their MSCE studying under Dr. Sriram Aaleti. While in their graduate programs, Hannah and Nathan individually studied UHPC applications in different topics of research. Hannah’s research focused on UHPC panels for impact-resistant tornado shelters with the goal of modeling their deflection response and recommending a minimum panel thickness. Using specifications from ICC/NSSA 500, high-velocity projectiles were shot at fiber-reinforced UHPC panels with the impact response captured by high-speed cameras. Nathan’s research focused on the application of UHPC in composite flexural members, specifically testing a UHPC/Timber prefabricated bridge deck used for short span members. This involved the testing of UHPC alone in flexure, UHPC in durability, a shear connection in UHPC to timber, and a final test of a scaled test sample meant to represent a true bridge deck flexure test. The goal of this research was to provide a proof of concept for a bridge deck replacement technique that could be quickly implemented and give the structure a higher capacity and a longer lifespan. During this period of graduate studies, Hannah, and Nathan both connected with companies in the UHPC industry. Hannah went on to accept a position as a Technical Service Engineer at National Cement while Nathan became a Project Engineer at Walo Civil. Since beginning work at these companies, the two have collaborated both in the field and in the office to help service the needs of the growing UHPC industry. In this presentation, Hannah, and Nathan hope to share their experiences as students and young professionals making the transition from academic contributions to real world applications.
