Seismic behavior of hider wing-walls

The Alaska Department of Transportation and Public Facilities (ADOT&PF) was awarded an $825,286 Formula Grant from the Federal Highway Administration's Highway Planning and Construction program (CFDA 20.205) on December 27, 2022. The grant funding will support research to develop tools for determining seismic demands on abutment wing walls, design details and analysis methods compatible with intended seismic performance, and recommendations for wing wall design. Deliverables under the award include a literature review, quarterly progress reports, an interim report, a final report, and technical advisory meetings as needed. The research outcomes will help ADOT&PF enhance the seismic resilience of highway infrastructure throughout Alaska.

Project description

Research to develop tools to determine the seismic demands experienced by abutment hider walls, develop design details and analysis methods for abutment hider walls that are compatible with the intended performance, and develop recommendations for design. Deliverables and tasks in this project include: a literature review, quarterly reports, an interim and final report and technical advisory meetings as needed.
