WORKFLOW

From Input to Results in Seconds

01

Define Section

Select C or Z section, input dimensions and steel grade. Section properties are computed instantly.

02

Set Spans & Loads

Enter bay spacing, span lengths, dead, live, collateral, and wind pressures. Add point loads as needed.

03

Run & Review

Analysis runs on the server. Inspect moment diagrams, deflection, unity checks, and export the full report.
