DrBeamPro

Dr. Beam Pro™ is a direct manipulation beam analysis environment. It differs from other beam analysis programs in that it is designed primarily for simulating and visualizing behavior as opposed to simply performing analyses.

Once you have learned to use Dr. Beam Pro n(5 - 15 minutes) designing a beam becomes as simple as applying loads and supports and watching what happens.
Dr. Beam Pro has additional features intended to make it more useful in a professional environment. These include two new tools for annotating the beam, a catalog of steel sections for design, and the ability to design with axial loads (beam/columns).
