Software for Precast Bridge Girder

Software for Precast Bridge Girder

Software for Precast Bridge Girder

(OP)
Can anyone suggest a reasonably priced software package for designing precast bridge girders? Our office does a few bridges each year but not enough to justify an expensive program. I would prefer one where non standard loadings can be used.

RE: Software for Precast Bridge Girder

Look at PSBeam from Eriksson Technologies

Leap software's CONSPAN is good but I think is more expensive.

Both companies offer leasing options for the software.  

Some state DOT's also have in-house programs that work adequately and are usually free. You would need to contact them directly to see how to gain access.  

RE: Software for Precast Bridge Girder

Florida DOT has a free Mathcad sheet for simple span prestressed concrete beams per AASHTO LRFD here:

Assuming you have Mathcad and use LRFD this is an option for you.  I’m not sure if it handles non-standard loadings, but since it’s in Mathcad you can modify the sheet as necessary for your design.

Another good resource for LRFD design is Washington State DOT. They have a prestressed girder analysis program (PGsuper) and HL-93 live load analysis program (QCON Bridge). These programs are free to download.

I have not used  the PGsuper program but have used QCON to run live load for a project I was working on. It worked well.

As MichSt and Tampa suggested the FLDOT mathcad sheet is a good starting point and you could always modify the sheet to use LFD, the design is essentially the same, just the loading changes.

Good Luck.
