AASHTO Guide Specifications for LRFD Seismic Bridge Design

AASHTO Guide Specifications for LRFD Seismic Bridge Design, 1st Edition, with 2010 Interim Revisions Covers seismic design for typical bridge types and applies to non-critical and non-essential bridges. AASHTO LRFD Design, AASHTO LRFD PDF

Approved as an alternate to the seismic provisions in the AASHTO LRFD Bridge Design Specifications. Differs from the current procedures in the LRFD Specifications in the use of displacement-based design procedures, instead of the traditional force-based “R-Factor” method.

AASHTO Guide Specifications for LRFD Seismic Bridge Design Includes detailed guidance and commentary on earthquake resisting elements and systems, global design strategies, demand modeling, capacity calculation, and liquefaction effects. Capacity design procedures underpin the Guide Specifications’ methodology; includes prescriptive detailing for plastic hinging regions and design requirements for capacity protection of those elements that should not experience damage.
Includes 2010 Interim Revisions, which can also be downloaded free of charge below.

The scope of these AASHTO Guide Specifications for LRFD Seismic Bridge Design for typical bridge types and applies to noncritical and non-essential bridges. The title of the document reflects the fact that the Guide Specifications are approved as an alternate to the seismic provisions in the AASHTO LRFD Bridge Design Specifications. These Guide Specifications differ from the current procedures in the LRFD Specifications in the use of displacement-based design procedures, instead of the traditional, force-based “R-Factor” method.

This new approach is split into a simplified implicit displacement check procedure and a more rigorous pushover assessment of displacement capacity. The selection of which procedure to use is based on seismic design categories, similar to the seismic zone approach used in the AASHTO LRFD Bridge Design Specifications. Also included is detailed guidance and commentary on earthquake-resisting elements and systems, global design strategies, demand modeling, capacity calculation, and liquefaction effects. Similar to the LRFD force-based method, capacity design procedures underpin the Guide Specifications’ methodology, and these procedures include prescriptive detailing for plastic hinging regions and design requirements for capacity protection of those elements that should not experience damage.

These Guide Specifications incorporate recent experience, best practices, and research results and represent a significant improvement over the traditional force-based approach. It is expected that these Guide Specifications will be revised as refinements or improvements become available.
