FB-MultiPier v4.12
The FB-MultiPier analysis program is a nonlinear finite element analysis program capable of analyzing multiple bridge pier structures interconnected by bridge spans. The full structure can be subject to a full array AASHTO load types in a static analysis or time varying load functions in a dynamic analysis. Each pier structure is composed of pier columns and cap supported on a pile cap and piles/shafts with nonlinear soil. This analysis program couples nonlinear structural finite element analysis with nonlinear static soil models for axial, lateral and torsional soil behavior to provide a robust system of analysis for coupled bridge pier structures and foundation systems. FB-MultiPier performs the generation of the finite element model internally given the geometric definition of the structure and foundation system as input graphically by the designer. This allows the engineer to work directly with the design parameters and lessens the bookkeeping necessary to create and interpret a model.


FB-Pier v3.21
The FB-Pier v3 program has been replaced by FB-MultiPier v4 and is no longer for sale or renewal. The program files are still available for license holders. Please look into FB-MultiPier - Single Pier w/o Dynamics option for a equilivant replacement.

FB-Deep (Formerly Shaft-SPT) v1.23
The FB-Deep computer program is a Windows based program used to estimate the static axial capacity of drilled shafts and driven piles. The methodology is based upon Federal Highway Administration (FHWA) reports. FB-Deep guides the user through pile and shaft materials data, shape and dimensional inputs, soil properties, and boring log info. FB-Deep then computes drilled shaft or driven pile capacity in clays, sands, and intermediate geomaterials, provides settlement analyses, and load transfers. FB-Deep presents the data analysis in both clear graphical and text form. Among its advantages over competitors’ software is FB-Deep’s emphasis on user efficiency. The first screen the user sees is also the most important, serving as the program’s control center, so the user doesn’t waste time finding their way through the program.


Brufem v4
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.


Atlas v5.04
ATLAS is an analysis/design program which is used for the analysis and design of signal lights and signs supported by the dual cable system. The analysis consists of an iterative technique which is a combination of the Force Density Method (FDM) and the Direct Stiffness Method (DSM). The FDM is ideal for the analysis of cable structures whereas the DSM is the most widely used technique for the analysis of framed structures. The nature of the structures under consideration lead to the development of this analysis technique which is a combination of the two methods. ATLAS handles the wind loading in a realistic manner. It allows the user to specify the wind speed as well as the areas of the signal lights or signs, parallel to the X and Y axis. In doing so the program calculates the applied loads on the corresponding nodal points internally, based on the specified element areas of the LIGHT elements in each plane. The loads are calculated in each cycle of the nonlinear process. Therefore, the applied loads in each cycle change with the rotation angle of the light. Thus the load are more realistic since they change with the swinging of the light. The angle change of the light also causes an uplift load at the cable nodal points.

Version 5 is now available. This version offers an easier to use, true Windows interface for creating models. Poles, cables and lights can be chosen using standard Windows dialog boxes. Controls and options are available using standard Windows menus and buttons. Some additional control has been added to allow different pole foundation height. It can read and run all old files.
