Introduction -- section 2. Definitions and notation -- section 3. General requirements -- section 4. Analysis and design requirements -- section 5. Analytical models and procedures -- section 6. Foundation and abutment design -- section 7. Structural steel components -- section 8. Reinforced concrete components -- References -- Appendix A: Foundation-rocking analysis -- Appendix B: Design flowcharts.Covers seismic design for typical bridge types and applies to non-critical and non-essential bridges. 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. 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.--Source other than Library of Congress.AASHTO Guide Specifications for LRFD Seismic Bridge Design BridgesDesign and constructionSpecificationsUnited StatesBridgesEarthquake effectsEarthquake resistant designStructural analysis (Engineering)Handbooks, manuals, etcEarthquake hazard analysisStrains and stressesElastic analysis (Engineering)Load factor designSoil-structure interactionSoil mechanicsShear strength of soilsShear flowSeismic wavesDampingEnergy dissipationBridgesDesign and constructionSpecificationsBridgesEarthquake effects.Earthquake resistant design.Structural analysis (Engineering)Earthquake hazard analysis.Strains and stresses.Elastic analysis (Engineering)Load factor design.Soil-structure interaction.Soil mechanics.Shear strength of soils.Shear flow.Seismic wavesDamping.Energy dissipation.American Association of State Highway and Transportation Officials.Subcommittee on Bridges and Structures,BOOK9911006506403321AASHTO Guide Specifications for LRFD Seismic Bridge Design4388777UNINA
