Basic Software 1

[sqrt]

Will anyone recommend a basic design software for creating moment and shear envelopes. There are a number of free programs that will analyze continuous beams, but I haven't seen one that will account for support stiffness. Also software that is not flexible in load definition, for instance only AASHTO design vehicles is an annoyance.

I used Risa 2D, which is quite basic package for analysis and design and has all the capabilities you described in your post. You can download demo from their website at

The Florida DOT has a free Mathcad worksheet that accounts for support stiffness and allows user defined trucks.
