摘要

The recently completed NCHRP Research Project 12-79, "Guidelines for Analytical Methods andErection Engineering of Curved and Skewed Steel Deck-Girder Bridges," investigated the analysis ofcurved and skewed steel girder bridges. Over 70 bridges were analyzed in detail using a variety of 1D,2D, and 3D analysis methods; for each bridge the results of the various analysis methods were comparedto benchmark 3D fine element analysis results or to field measurements (when available) to evaluate theiraccuracy. The results were evaluated to determine appropriate levels of analysis for erection engineeringof various types of steel girder bridges. Approximate analysis methods such as line girder and gridanalyses still provide value when used appropriately, and many engineers are more comfortable usingthem than using more complicated and time-consuming 3D methods; the results of this research providequantitative guidance on appropriate applications of these approximate methods. Numerous findings andrecommendations representing significant advancements in the state of the art for erection engineeringwere generated. While a few of the recommendations involve improvements to commercial bridgeanalysis software and may take some time to implement, the remainder of the findings andrecommendations can be implemented immediately by bridge engineers performing erection analyses.The NCHRP 12-79 research team provided a succinct and practical summary of these immediatelyimplementable findings and recommendations, in a format useful to practicing bridge design engineers, inthe form of Appendix B of NCHRP Report 725. This paper provides a summary of the NCHRP Report725 Appendix B recommendations.
