What is structural analysis software?

Structural analysis and design software evaluates a structure’s ability to withstand external loads and to meet design code requirements.

Visit the top of a skyscraper, sit in a sports stadium, drive over a bridge, walk through a warehouse, factory, school, hospital or any large structure and know you’re on solid footing because they are engineered to be structurally sound.

Since 1981 S-FRAME Software’s contributing role in this essential engineering process is to develop and support the structural analysis and design software used by engineers.

Our mission is to provide software that helps engineers produce Robust Designs: designs that are less sensitive to loading variations and deviations from the intended design specifications during a structure’s life cycle by evaluating your model’s response to wind, snow, water, linear, non-linear, seismic, blast, self-weight, moving loads or other dynamic loading conditions.

Why are we called S-FRAME Software?

“S” is for spacial frames, hence the name S-FRAME Analysis, first released in 1984. Since then S-FRAME Analysis has evolved into a powerful, 3D finite element structural analysis software platform that includes steel design, concrete design, foundation design and timber design.




Analyze, design and detail structures with confidence, regardless of geometric complexity, material type, loading conditions, nonlinear effects, or design code requirements.

Supporting over 10,000 clients working in 70+ countries, our team of developers and application engineers, most who are expert M.S. and Ph.D.-level engineers, are committed to providing best-in-class technical support.
