| 摘要： | The Texas Department of Transportation (TxDOT) is currently designing highway bridge structures using the American Association of State Highway and Transportation Officials (AASHTO) Standard Specifications for Highway Bridges, and it is expected that the agency will transition to the use of the AASHTO LRFD Bridge Design Specifications before 2007. This is a two-volume report that documents the findings of a TxDOT-sponsored research project to evaluate the impact of the Load and Resistance Factor (LRFD) Specifications on the design of typical Texas bridges as compared to the Standard Specifications. The objectives of this portion of the project are to evaluate the current LRFD Specifications to assess the calibration of the code with respect to typical Texas prestressed bridge girders, to perform a critical review of the major changes when transitioning to LRFD design, and to recommend guidelines to assist TxDOT in implementing the LRFD Specifications. / NOTE: Technical rept.
