Abstract:This manual provides guidance on performing refined analysis of bridges. The manual describes “refined analysis” and the methods allowed by the American Association of State Highway and Transportation Officials (AASHTO) Load and Resistance Factor Design (LRFD). Guidance for the modeling of typical girder bridges at various levels of complexity are provided. Additional guidance is provided for modeling prestressed and post-tensioned concrete girder bridges, fatigue and mechanical connections in steel bridges, and modeling of substructures as well as for more advanced topics such as soil-structure interaction and nonlinear and dynamic analyses. Methods and examples of verifying and validating the output from an analysis software are provided. Discussion of the various loads bridges are subjected to and how to apply the loads in refined analyses is included. The last chapter discusses how to take the results from the refined analysis and go forward to the design of a structure. Also included are seven example problems and comparison of the results from different levels of analysis. The seven examples are: (1) Three-span, Precast Concrete I-Girder Bridge made continuous for live load; (2) Three-span Continuous Steel I-Girder Bridge; (3) Three-span Continuous Curved Steel I-Girder Bridge on skewed supports; (4) Three-span Continuous Concrete Box Girder Spine Beam; (5) Dynamic Analysis of a Curved Steel Girder Bridge; (6) Stability Analysis of a Tall Concrete Pier Column; and (7) Four-span Continuous, Precast Segmental Concrete Box Girder Bridge.
