BridgeTech’s Role:

BRASS-GIRDER™ is a program that performs a comprehensive design review or rating of highway bridge decks and girders using plane frame analysis.  Simple-span, continuous-span, and frame structures composed of steel, prestressed concrete, reinforced concrete, and timber girders are supported.  Specification checks are performed using the AASHTO LFD or LRFD analysis methods. Program results include section properties, dead load distribution, live load distribution, unfactored/factored dead and live load actions, numerous specification checks, and design ratios or rating factors.  Additionally, NCHRP 12-50 report IDs are provided for many of the key analysis results.
