Dr. Jim Nau joined the Department of Civil, Construction, and Environmental Engineering in 1982 after receiving his Ph.D. degree from the University of Illinois at Urbana-Champaign. At the undergraduate level, he teaches statics, solid mechanics, reinforced concrete design, structural steel design, and the senior design project course. At the graduate level, he teaches CE 523 Theory and Behavior of Steel Structures and CE 528 Structural Design in Wood.

Research Description

Dr. Nau is interested in structural design, structural dynamics, earthquake engineering, and numerical methods. His research is principally in the area of earthquake engineering. He is currently engaged in several research projects on the seismic response of steel and concrete bridge structures, with support from the Alaska University Transportation Center and the Alaska Department of Transportation. In collaboration with colleagues Mervyn Kowalsky and Rudi Seracino, this research involves large-scale experimentation at the Constructed Facilities Lab. Dr. Nau's research interests have recently expanded to include structural repair using fiber reinforced polymer (FRP) materials. Reinforced concrete columns tested as part of a AUTC/AKDOT project have successfully been repaired to restore strength while preserving ductility.
