The California Department of Transportation (Caltrans) has developed CTBridge to replace the aging BDS program.  CTBridge supports the Caltrans version of the LRFD specifications and boasts an easy-to-use graphical interface.  Unlike BDS, the CTBridge model is three dimensional.  CTBridge has been used internally for several years, and is now publicly available for $2500.

The Washington Department of Transportation (WSDOT) has developed this prestressed concrete girder program.  This robust, FREE, program has a fully interactive graphical interface, and supports AASHTO LRFD specifications.  This is the mainstay prestressed I-girder program for WSDOT designers.  This program is definitely worth the time to check out.

 

 

 

 

 

 

The State of Pennsylvania (PennDOT) has developed a concrete prestressed girder (PSLRFD) program and a steel superstructure (STLRFD) program.  Both of these inexpensive, yet comprehensive, programs support the AASHTO LRFD specifications.  Note that these programs are specifically written for PennDOT needs.
