Guide Specifications and Commentary for Vessel Collision Design of Highway Bridges

AASHTO Guide Specifications and Commentary for Vessel Collision Design of Highway Bridges 2nd Edition 2010 Interim Revisions This 2nd Edition of the Guide Specification was developed to incorporate lessons learned from the use of the original 1991 Vessel Collision Guide Specification; incorporate the current LRFD Bridge Design methodology; clarify some of the risk procedure elements; make minor modifications and corrections; and to discuss, and incorporate where deemed necessary, results from barge and ship collision research conducted since the original vessel collision publication.

AASHTO Guide Specifications and Commentary for Vessel Collision Design of Highway Bridges 2nd Edition 2010 Interim Revisions The use of the Guide Specification procedures to evaluate existing bridges has been highlighted in this revised edition, and a new worked example illustrating the vessel collision risk assessment procedures has been provided.
This edition developed in U.S. Customary Units.

The 1980 collapse of the Sunshine Skyway Bridge was a major turning point in awareness and increased concern about vessel collision and the safety of bridges crossing navigable waterways in the United States. Studies initiated as a result of this tragedy led to the 1988 pooled-fund research project sponsored by 11 states and the Federal Highway Administration (FHWA) which developed a proposed design code for use by bridge engineers in evaluating structures for vessel collision. This effort culminated in 1991 with the adoption by the American Association of State Highway and Transportation Officials (AASHTO) of the Guide Specification and Commentary for Vessel Collision Design of Highway Bridges (AASHTO, 1991).

The 1991 AASHTO Guide Specification established design provisions for bridges crossing navigable waterways to minimize their susceptibility to damage from vessel collisions. The provisions applied to both new bridges and to the analysis of existing bridges to determine vulnerability and potential retrofit. The intent of the AASHTO provisions is to provide bridge components with a “reasonable” resistance capacity against ship and barge collisions.

AASHTO Guide Specifications and Commentary for Vessel Collision Design of Highway Bridges 2nd Edition 2010 Interim Revisions In navigable waterway areas where collision by merchant vessels may be anticipated, the Guide Specification requires that bridge structures be designed to prevent collapse of the superstructure by considering the size and type of vessel fleet navigating the channel, available water depth, vessel speed, structure response, the risk of collision, and the operational classification of the bridge.
