Title:Sustainable Alternative to Structurally Deficient Bridges
Principal Investigators:Junwon Seo and Nadim Wehbe
University:South Dakota State University
Grant #:69A3551747108 (FAST Act)
Project #:MPC-576
RH Display ID:15397
Keywords:bridge construction, bridge design, girder bridges, laminated wood, prototypes, structural analysis, timber construction


Structurally deficient bridges in the United States may be replaced with a viable alternative made with Cross Laminated Timber (CLT). The alternative promotes environmental sustainability, diversified wood production opportunities, and increased public safety and construction efficiency. CLT products' superior strength, durability and sustainability have led to commercialization for building applications, but CLT has never been applied to bridge systems. The ultimate goal of this project is to improve bridge sustainability and performance using CLT products. To achieve this goal, researchers will pursue the following research objectives: 1) conceptualize a new CLT girder bridge system; 2) design and manufacture the full-scale specimen; and 3) investigate structural performance of the bridge system. To succeed, one CLT fabricator, who serves as an industrial collaborator on this project, will provide practical input for the production of the specimen. Further, one graduate student will gain hands-on research experience and real-world solutions. The PI will integrate the findings into SDSU engineering courses, including CEE 792: Bridge Engineering, to introduce students to CLT bridge performance.
