| Bridges for Service Life Beyond 100 Years: Innovative Systems, Subsystems and Components (SHRP 2 Project R19A)* |
|
Greetings!
Designing bridges for enhanced service life is increasingly important as demands on resources grow. Addressing service life issues at the design stage is significantly less costly than taking maintenance and preservation actions while a bridge is in service. However, design for service life must be approached systematically, using a general framework that can apply to all bridges while also allowing for specifics that are unique from one bridge to another.
SHRP 2 project R19A, Bridges for Service Life Beyond 100 Years: Innovative Systems, Subsystems and Components, developed the Design Guide for Bridges for Service Life to provide information about and define procedures for systematic approach to designing for service life and durability for both new and existing bridges. It includes new concepts and approaches that offer improvements to current practice and have the potential to enhance the service life of bridges. This final report details how the Guide was developed and provides results from extensive individual research efforts leading to new details and concepts that can mitigate factors that have historically limited service life of bridges. The Design Guide is also available as a pre-pub.
*To make research available as early as possible, SHRP 2 is temporarily posting final reports that have been submitted by the research team, reviewed according to the relevant National Academy of Sciences procedures, and accepted for publication. These prepublication drafts, which have not been edited or formatted for publication, will be replaced by the final versions as the complete the editorial process.
