Analysis, Design, Rating, and Drafting of Wood Bridge Superstructures

A program for engineering wood bridges is described. The program performs the analysis, design, and/or rating of wood bridge superstructures in accordance with the 15th Edition of the AASHTO Specification or the AASHTO-LRFD Specification. Bridges may be analyzed for design review and/or rating. In review/rating mode, the superstructure is analyzed and checked against all applicable specifications. In the design mode, minimal user input, such as span length, roadway width, bridge type, and materials are entered and the program reviews designs and issues details associated with standard plan sets. The appropriate design-specific information is included in a DXF format for inclusion into the final drawings. A Microsoft Windows-based user interface is used for the data definition. The data is passed to another module for engineering computations. The associated documentation is contained in both on-line and hard copy formats. The most commonly used bridge and deck systems are accommodated in either U.S. customary or SI units.
