Nonlinear Seismic Response Analysis of Isolated Bridges with Multiple Columns
A nonlinear computer program to predict the dynamic response of base isolated bridges to orthogonal, horizontal earthquake ground motions was developed. The computer program can model multi-span bridges with straight, continuous superstructures and multi-column bents. Hysteretic behavior of elastomeric or lead-rubber isolators, abutments, shear keys, and columns can be modeled. Nonlinear analysis of the six-span Verdi bridge near Reno, Nevado showed that column ductility demands can be eliminated using isolation. Studies were conducted to show that seismic isolation may not be effective in bridges with long columns and located on deep soil deposits. The AASHTO Guide Specifications for Seismic Isolation Design were evaluated.
