STEEL Structural Design and Optimization Software
Use S-STEEL to code check and auto design steel members for both strength and serviceability to ensure structural safety and economy.
Optimize steel members based on an extensive list of optimization criteria, design codes, and constraints so that you can satisfy your design and performance assessment needs.
Comprehensive engineering reports in graphical and tabular format include design results, interactive formulas, equations, and graphics.

The S-STEEL Design Interface
S-STEEL Design is an add-on module to S-FRAME Analysis. S-STEEL supports staged construction, composite beam design, linear and nonlinear static, response spectrum, linear and nonlinear time history (including base and multi-support base motion), linear and non-linear moving-load analyses. Access all S-FRAME Analysis features, including the powerful model management system (folder technology, selection options, shortcut tools, S-VIEW’s model validation, and more) within a single work environment.
Quickly locate and assess critical areas requiring re-design. Select specific members using multiple filtering options.
Override section sizes for all members or a subset of members and immediately see if they pass or fail the code checks, why, and by how much.
Structural Steel Design Options
Multiple settings and options exist to meet preferences and or requirements in your design workflow, from displaying the design results, to the level of detail, or format of Code Details.
Users can instruct S-STEEL what to do when changes were made to analyzed section, before returning to S-FRAME Analysis.
Steel Design Reports
Generate company-branded, customized reports in graphical or tabular format.
Comprehensive steel design results include equations and clause references for members that pass or fail with users having the options to show as much information as possible, or only the results that are relevant to the problem in hand.

Recent Enhancements in S-STEEL R2021.1
- New Advanced Composite Beam Design Capabilities
- Both longitudinal and perpendicular deck rib orientations are supported.
- Physical and Analytical Members (or a mix thereof) are supported
- Automatic calculation of optimal stud length
- Girders with dual spanning decks, including strength, serviceability, stud size and stud spacing requirements
- S-STEEL calculates the optimal Segmental Stud Spacing on girders with intermediate concentrated loads and graphically displaying the stud distribution between concentrated loads.
- S-STEEL calculates the optimal rib orientation and effective widths based on perimeter beam spacing and lengths as per code requirements for both interior and exterior beams with optional accounting for overhangs on exterior spans and floor openings.
- Sloped Floors and beams do not have to be orthogonally arranged in the effective width calculations – nor is it necessary to conform to a rigid member connectivity system
- S-STEEL computes the lateral torsional buckling unsupported top and bottom lengths for both composite and non-composite stages based on intermediate framing members and composite and non-composite properties.
- Round-tripping to S-FRAME Analysis for both composite and non-composite stages. Section properties based on effective widths are automatically updated for the composite stage while optimal steel sections are maintained for both stages.
- Support for user specified minimum % shear connection and maximum % shear connection with the option to modify minimum % shear requirements based on member length (as per code requirement)
- Support for flange thickness checks based on stud diameter welding requirements.
- Automatic camber calculations including support for % dead load reduction, serviceability checks based on NET cambered deflections, ability to optionally exclude camber for cantilever beams or beams where depth or length are controlling factors.
- Automatic determination of effective widths, camber, rib orientation, uniform or optimal stud spacing, can optionally be modified by the user on a member by member basis.
- All composite data can be either imported from or exported to an MDB file.
- Composite group data can be defined and automated design based on both strength and serviceability requirements can be performed for each group based on the above mentioned optimization options for each group.
