Researchers Learn How Impacts to Bridge Columns Affect Future Performance in Earthquakes
Posted: Dec 9, 2024
Researchers at Utah State University examined how the vital connections between bridge components used in accelerated bridge construction react to vehicle impacts and how those impacts affect any subsequent earthquake activity. They found that the location of those connectors within columns and footers plays a crucial role in enhancing the column’s resistance to both impact and seismic loads. The research can help determine the residual seismic capacity of the columns after an impact event, guiding the assessment and necessary reinforcement measures to ensure structural integrity and safety in future seismic events.
