This book covers seismic design for typical bridge types and applies to non-critical and non-essential bridges. It is approved as an alternate to the seismic provisions in the AASHTO LRFD Bridge Design Specifications. This 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. It 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 Specificationsβ methodology; includes prescriptive detailing for plastic hinging regions and design requirements for capacity protection of those elements that should not experience damage.
Included in this electronic edition are the 2012 and 2014 Interim Revisions. Following each chapter the Revisions are identified as well as linked throughout the entire book where available. See the "Interim Revisions" sections for a complete list of changes to each section.
