Design Criteria for Theater of Operations Glued-Laminated Timber Highway Bridges. Volume I.

摘要

This report presents structural design criteria recommendations for theater of operations (T/O) temporary glued-laminated timber highway bridges. The report consists of two volumes: Volume I provides the design criteria, procedures, and material specifications, and Volume II contains the development of and justification for the criteria in Volume I. State-of-the-art methodologies were used to develop the criteria, which are based on modifications to existing military and permanent criteria. Use of the criteria by engineers in bridge design offices should result in T/O bridges that have adequate safety and perform satisfactorily. Material weight of glued-laminated timber stringers in T/O bridges designed using the recommended criteria, typically will be about 15 percent less than when designed using permanent bridge criteria.
