Accuracy of steel fabrication - SteelConstructionfoSpecial tolerances. Individual projects may specify special tolerances, either as a modification of the essential or functional tolerances or for aspects not already covered. There is a need for certain additional tolerances on most bridge structures, and these should generally be implemented via the Specification for Highway Works.

How to Design a Bridge Bridge Structural Designing StepsThe designer should have first seen and studied many bridges in the course of a long learning process. He should know what type of beam may be suitable in the available conditions, either a beam bridge an arch bridge or a suspended one. He should also know the influence of foundation conditions on the choice of spans and structural systems etc. hence, the designer
This document consists of a comprehensive steel girder bridge design example, with instructional commentary based on the AASHTO LRFD Bridge Design Specifications (Second Edition, 1998, including interims for 1999 through 2002). The design example and commentary are intended to serve as a guide to aid bridge design engineers with the implementation
