Improvements on ARA’s prior SDOF tool include additional built-in models, additional SDOF boundary conditions and load condition, additional analysis options, a more robust units system, additional time step and analysis duration options, and a built-in calculator allowing basic math to occur in any input cell.

Specific Features:

• The ability to develop reusable libraries of load functions, PI curve criteria sets, material properties, and beam cross sections.
  • Built-in material library containing common steel and aluminum properties.
  • Built-in shapes database containing common wide flanges, channels, angles, structural tees, HSS sections, SSMA studs and tracks, Joist, and CMD shapes.

• Many Built-in SDOF models
  • Several Component Types
    • Metal Beams
    • Reinforced concrete beams and slabs, including Type I, Type II, and Type III sections. Precast steel options are also included.
