Structural engineering, simplified

Accurate structural analysis, without the spreadsheet chaos

SES replaces error-prone manual calculations with fast, engineer-built tools for gravity, load paths, column design, and axial shortening — all in one place.

Engineering tools that work the way you think

From tributary areas to axial shortening — purpose-built calculators for real structural workflows.

View all tools
Gravity
Analyze vertical load systems and tributary areas.

Comprehensive toolkit for analyzing vertical loads, tributary areas, and designing gravity-resisting structural elements.

Load Run Down
Calculate cumulative load run down across floors in a structure.

Analyze vertical load transfer throughout buildings, accounting for different tributary areas and load types.

Column Design
Design reinforced concrete columns based on loads and moments.

Design optimal rectangular or circular reinforced concrete columns with considerations for both strong and weak axis loading.

Axial Shortening
Construction-sequence axial shortening with creep and shrinkage per AS3600.

Compute per-level elastic, creep and shrinkage shortening for tall concrete columns or walls, accounting for the construction sequence.

How it works

Three steps from model to results — no macro-enabled workbooks required.

1
Define your structure
Set up floors, grids, and load cases — or jump straight into a standalone tool for quick checks.
2
Run the analysis
Let SES handle tributary logic, load accumulation, member design, and time-dependent effects automatically.
3
Review and export
Inspect clear outputs, iterate on inputs, and take results back to your project documentation.
