What you get
From the loads to a finished pr moment
The applicable limit states, checked
Strength and detailing checks to AISC 360-22 and the 16th Edition Steel Construction Manual, each with its ratio, the clause or equation it comes from, and the governing case. Results update as you type.
Drawings to scale
Elevations, plans and sections with bolts, weld symbols and dimensions, on a drawing sheet with your title block, as PDF or DXF.
A calculation report a reviewer can follow
Inputs, every check with its result and reference, and the governing case, in a clear PDF. See a sample report.
LRFD or ASD, US or SI
Switch the design method and the units at any time; the drawings and the report follow. Auto-design proposes a layout you can fine-tune.
Verification
How the pr moment is tested
No AISC worked example is published: hand calculations from the cited equations, and the stiffness model against Kishi and Chen (1990) and Kishi, Chen, Goto and Matsuoka (1993).
How the types without a published worked example are checked.
