From the frame to every joint.
An 18 m steel portal frame: 4 bays of 6 m, 6 m eaves, 10° roof, UC254x73 columns, UB406x60 rafters with eaves and apex haunches, cold-formed purlins and girts, sag rods, wall and roof bracing. One model in STATIX: analysis, member design and connection design, with every check shown. These are the real results, not a mock-up.

One model, start to finish.
No forces typed from one program into the next. Each step reads the one before.

Model, analysis and member design
The frame, its loads (dead, live, wind uplift, side wind, wind along the gable) and 5 load combinations in one 3D model. The analysis feeds the member design directly: columns, rafters and braces are checked to SANS 10162-1, the cold-formed purlins and girts by the direct strength method. Result: 131 member groups, none failing; the highest is a cold-formed girt at 90 %.

Connection design on the same model
STATIX finds every joint in the solved frame and checks it with the member forces from every combination: haunches, base plates, purlin and girt cleats, sag rods, brace gussets and crossings, eaves struts and fly braces. 295 joint checks of 14 types, every one with its clause.

Out to Advance Steel for detailing
The fabrication export takes the designed joints, plates, bolts and welds to Advance Steel: 267 joints, none skipped. The detailer starts from the checked design instead of redrawing it.
Every joint type, checked.
