Seismic Design of Bridges Design Example No. 3: Single Span AASHTO Precast GirderBridge

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 third example is a skewed 70 feet single span prestressed concrete girder bridge with tall-closed seat-type abutments on spread footings, SPC-C & A equals 0.36g.
