Project detail
Roadmap/Focus area(s):   Infrastructure Research and Technology Strategic Plan and Roadmap
Project Description:   Federal Highway Administration envisions reducing the construction/maintenance time of new and existing highway structures to increase mobility and safety of┬áthe surface transportation system. In reducing the construction/maintenance time, accelerated construction technology and methodologies are essential to the success of this mission. However, applying accelerated bridge construction technology to high-seismicity areas requires more sensitive connection details to accommodate the large ground motions than in other areas. Innovative technologies and their applications are continuously sought to refine and expand connection details and their applicability to enhance seismic performance. This project will develop the necessary bridge connection details to be used in moderate-to-high seismic areas, ensuring constructability as well as effectiveness.
Goals:   The objective of this study is to improve the seismic resistance of our highway system by developing seismic design details (to be used in accelerated bridge construction projects).
Product Type:   Research report
Test Methodology:   The study will focus on the segmental bridge column construction, and a reduced-scale bridge column model will be tested using a shake table to develop effective design details. Developing innovative technologies that can enhance the seismic performances of precast reinforced concrete bridges with emphasis given to accelerated bridge constructions. This includes the development of roller isolation bearings and the structural fuses developed and used in buildings for the seismic retrofit of bridges. Conducting series of workshops and conferences for technology exchange, which includes the national seismic conferences for bridges and highways.
Other Information:   This study is a congressionally mandated research project under the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users.
Expected Benefits:   Improve seismic safety of bridges.
Deliverables: Name: Seismic Design Details.
