Ensures the overall structural integrity of the bridge under statistically determined load combinations.
The is a comprehensive technical standard established for the design, evaluation, and rehabilitation of both fixed and movable highway bridges in the United States. Published by the American Association of State Highway and Transportation Officials (AASHTO), this edition refined the Load and Resistance Factor Design (LRFD) methodology, which utilizes statistical knowledge of loads and structural performance to ensure uniform safety across different bridge types. Core Philosophy: The LRFD Methodology Ensures the overall structural integrity of the bridge
Restricts stresses and deformations under regular use to ensure durability and serviceability. Core Philosophy: The LRFD Methodology Restricts stresses and
