• Abstract:
  The purpose of this set of guidelines is to summarize recommendations from work ; completed as part of the Texas Department of Transportation (TxDOT) Research Project 0-5574 ; entitled "Curved Plate Girder Design for Safe and Economic Construction." The research ; included field tests, three-dimensional finite element parametric studies, and software ; development. The full report for the study will be submitted by October 31, 2009 and includes a ; more detailed explanation of the recommendations given within this document. ; The development of general guidelines to ensure girder stability during lifting, erection ; and early stages of construction is complicated by the wide range of variables that impact the ; behavior of the girder system. These variables include girder proportioning, partially installed ; bracing, crane positioning, the use and positioning of temporary supports, as well as several ; other factors. To aide in assuring girder stability, two analytical tools were developed as part of ; this research project. The analytical tools consist of a spreadsheet program (UT Lift) for ; evaluating girder behavior during lifting, and a finite element program (UT Bridge) for analyzing ; the behavior of I-girder bridges at various stages of erection and during construction of the ; concrete bridge deck. While the guidelines presented herein have been developed to assist in ; producing a stable system, the reader is encouraged to use the analytical tools, UT Lift and UT ; Bridge, or other suitable analytical packages, to evaluate bridge girder systems during ; construction.
