Dr. Lesley Sneed, associate professor of civil, architectural and environmental engineering, has been recognized by the American Concrete Institute for moving building codes forward. Sneed served as principle investigator of a project titled “Interface Shear Transfer of Lightweight Aggregate Concretes with Different Lightweight Aggregates.” The findings from this research proposed revisions to the next edition of the ACI 318 code and PCI Design Handbook for shear-friction design provisions of a smooth interface condition.
