Computer Design and Analysis of Steel Box Girder Bridges for Transit Structures

摘要

The purpose of this study is to develop design criteria and a computer program which can be used to design/analyze straight or curved single or multi composite box girder bridges for transit structures. The resulting computer program will perform an analysis or design of a single prismatic or nonprismatic straight or curved box girder when subjected to a specified train loading. The train loading may be any series of coupled units. The box section is a single unit of the bridge or a member of a multiple box system. The box may be non-composite or composite construction. The section can have internal transverse diaphragms spaced along the box and top lateral bracing.
