Title LRFD-Based Analysis and Design Procedures for Bridge Bearings and Seismic Isolators.
Publication Date Sep 2011
Media Count 436p
Personal Author A. Filiatrault I. Kalpakidis M. C. Constantinou R. A. Ecker Lay
Abstract This report describes the development and application of analysis and design specifications for bridge bearings and seismic isolators that (a) are based on the LRFD framework, (b) are based on similar fundamental principles, which include the latest developments and understanding of behavior, and (c) are applicable through the same procedures regardless of whether the application is for seismic-isolated or conventional bridges. Examples are presented of design of conventional elastomeric and PTFE spherical bearings and three examples of detailed design and analysis of the seismic isolation system of a bridge located in California utilizing lead-rubber, single Friction Pendulum and triple Friction Pendulum isolators. The seismic isolation design examples utilize the latest definition of seismic hazard in California and intent to serve as a guide to application of the technology to bridges in California.
