BRUFEM

The BRUFEM program is used to perform automated finite element modeling, analysis, and load rating of highway bridges using a complete 3-D model. The program considers prestressed and steel girder, reinforced concrete T-beam, and flat slab bridges. Large numbers of potential vehicular loading conditions can be rapidly modeled then analyzed and automated rating based on the AASHTO bridge specification can be performed. Salod (Structural Analysis for Load Distribution) is a hybrid finite element program that creates an influence surface of simple span bridge superstructures. The current version uses text based, question prompts in order to develop an input file. The two primary modes of operation are Full Load analysis (including consideration of construction stages) for AASHTO load rating and Live Load analysis for calculation of lateral load distribution factors (LLDFs) There is an analysis engine, a rating post-processor and a graphics post-processor. System consists of four programs. The Preprocessor rapidly models bridge structures and loading conditions. The Finite element analysis engine computes structural response. The Post-processor computes LLDFs and rating factors based on AASHTO specifications. The Graphical post-processor displays analysis results graphically.
