Engineering researchers at the University of Nebraska-Lincoln have received a US$2 million grant to explore ways to make new and existing bridges last longer.
The grant from the National Academy of Sciences is aimed at identifying technologies and designs to renovate existing bridges and develop guidelines for designing longer-lasting new bridges. The focus will be on bridges with spans of 100m or less, which includes 95% of bridges in the USA.
The research will be led by civil engineering professor Atorod Azizinamini. He said the team will study whether the new generation of high-performance steel and concrete materials can be used for individual bridge components. The team also will identify construction strategies for helping engineers renovate existing bridges without causing major traffic disruptions.
