How it works

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

Define your structure

Set up floors, grids, and load cases - or jump straight into a standalone tool for quick checks.

Run the analysis

Let SES handle tributary logic, load accumulation, member design, and time-dependent effects automatically.

Review and export

Inspect clear outputs, iterate on inputs, and take results back to your project documentation.
