BRASS-TRUSS : Version 2.2   May 2016

The Working Stress Analysis (WSD) portions of this program is current with the AASHTO Specifications for Highway Bridges, 16th Edition, 1996, with Interims.


This is a system of computer programs designed to assist a bridge engineer in the analysis and load rating of simple or continuous truss or girder bridges with floor beams and stringers. It generates properties, computes truss coordinates and weights, analyzes each simple or continuous span for dead-load and live-load moments and shears, and determines the structural rating for each type of member submitted. This component was originally developed by the New York Department of Transportation.

BRASS-TRUSSTM has been developed and distributed through a cooperative effort between the WYDOT and the New York State DOT. It has been extensively tested by the New York State DOT.
