Where can I find some good software to simulate the stresses on a bridge?

Question

I am looking for a software where I can draw a bridge. Then I would like it to add stress to the bridge (i.e: add weight to it) and display where the bridge is receiving the most stress. If the software could demonstrate the areas in which the bridge is under tension or compression, it would be even better.

I have a vast experience with computers and a good amount of knowledge in the construction of bridges. I am ready to pay money, so don't limit yourselfs to freeware, please.

Thanks for your recommendations,

I wanted to add that this is not meant for large scale projects. I am mearly trying to simulate the stresses on basswood bridges.

Answer 1

Do a web search on the "finite element analysis," with some added qualifiers like "download." There are a number of free versions out there. If you want to buy the full-featured commercial versions, be aware that prices start out around the several thousand dollar price range. A finite element analysis software package will let you draw a structure, put loads on it, then it will tell you what the stresses are in it. It will do everything you want and more.

Answer 2

Bridges see the most bending stress in the middle of the span and the most shear stress at the ends. For truss type bridges, the top chord is in compression and the lower chord is in tension.

There is a free finite element program called cadre light. It will do all you need to do for a truss type bridge. If you are going to make girders or something else, then I would recommend STAAD.

Sap2000 is not a bad place to start for bridges.
