PERFORMANCE OF ACCELERATED BRIDGE CONSTRUCTION CONNECTION IN BRIDGES SUBJECTED TO ESTREME EVENTS

摘要

This paper summarizes the findings from NCHRP Project 20-68A, Domestic Scan 11-02on “Best Practices Regarding the Performance of Accelerated Bridge Construction (ABC)Connections in Bridges Subjected to Multi-Hazard and Extreme Events”. The objective of thisDomestic Scan was to identify connection details that can be used for ABC and which performwell under extreme events, including waves and tidal or storm surge loads, earthquakes, blast,and other large lateral forces. Topics covered include findings on published ABC designguidelines, standard ABC components and connections, research results, field case studies,lessons learned, and Scan Team recommendations.
