• Competitive State-of-the-Art Structural Engineering

      The University of Alaska Fairbanks College of Engineering and Mines has a legacy with the Steel Bridge Competition. Each year, since starting nearly three decades ago, the university has pushed the limits of the competition through vigorous ingenuity and teamwork. Having a small team, where funding is hard to come by and manufacturing is all done in-house, the team would seem to be at a disadvantage. However, the team has used their obstacles as challenges to overcome rather than to deter them. Through various community outreach activities, volunteering, and professional networking the Steel Bridge team gets involved with Fairbanks and raises enough funds for materials and travel to the Pacific Northwest and then onto National Conferences. Through in-house fabrication, the Steel Bridge Team learns hands on welding and design testing, and the value of transparency between design and construction. The team also focuses on building itself, developing the people around them into better, well-rounded, well-spoken and hardworking engineers of Alaska’s future.
    • Wearing Surface Testing and Screening: Yukon River Bridge

      There is a demand and a need for cheaper and alternative surface coverings in environments with high temperature fluctuations. Our design for an alternative surface covering involves a basic twopart component epoxy with the addition of a solvent. The purpose of the solvent is to disrupt the reaction that forms the ordered chains to form a more disordered crystalline structure. The solvent in the finished product is 3% by volume of isopropyl alcohol. This mixture of epoxy and solvent has higher impact strength than epoxy alone, as well as a much lower brittle transition temperature of 27°C compared with 10°C for epoxy. An environmental chamber, tensile tester, Charpy impact tester, and 4- point bending test were used to determine these conclusions. The final product can be tailored with different aggregates to fit a specific need, such as decking surface material to coat the wooden planks on the Yukon River Bridge.
