Seismic Design of Bridges. Design Example No. 7: Twelve-Span Viaduct AASHTOPrecast Concrete Bridge

摘要

This document describes one of seven seismic design examples that illustrate'how' to apply AASHTO's seismic analysis and design requirements on actual different bridge types across the United States. Each provides a complete set of 'designer's notes' covering the seismic analysis, design, and details for that particular bridge including flow charts, references to applicable AASHTO requirements, and thorough commentary that explains each step. In addition, each example highlights separate issues (skew effects, wall piers, elastomeric bearings, pile foundations, etc.). The seventh example is a 717 feet 10-span prestressed girder bridge with open pile bents, SPC-B & A equals 0.10g. The superstructure consists of three continuous span units arranged in a 3-4-3 span series.
