The RSTAB add-on module FRAME-JOINT designs rigid-bolted connections between columns and beams and classifies them. These joints are analyzed with the ultimate load design method (determination of the plastic capacity according to DIN 18800) following the plastic verification procedure of Eurocode 3, Annex J.
To realize economical connections, web plate strengthening stiffeners and backing plates are only applied when inevitable to absorb the ultimate load.

Program Features

• Knee joint on inclined and right-angled frame corners
• Flush end plate joints, inclined column end optional
• Simple input of the haunched geometry
• Column and beam sections from customary or cut rolled girders and singly or doubly symmetrical welded girders
• Bolts of the strength grades 4.6, 5.6, 8.8 and 10.9, adjustable hole clearances, selectable bolt threads in or out of shear plane, drilled or punched holes
• Bolt spacing customizable: uniform, iterative, or through a defined area in the tension zone
• Two vertical bolt rows, number of the horizontal rows only limited by the web height (tension zone)
• Determination of the optimum connection geometry, end plate thickness, backing plates, stiffeners, column web plate strengthening, diagonal stiffeners, welds
• Adjustable specification with regard to the thickness of end plate, backing plate, diagonal stiffeners and to the disposition of web stiffeners and column web strengthenings
