JOINTS Steel – Column Base

The Hinged Column Footing category provides four different base plate connections:

• Simple column base
• Tapered column base
• Column base for rectangular hollow sections
• Column base for circular hollow sections

The Restraint Column Footing category provides five different joint layouts of I-sections:

• Base plate without stiffening
• Base plate with stiffeners in center of flanges
• Base plate with stiffeners on both sides of column
• Base plate with channel sections
• Pocket foundation

All connection types include a base plate welded around a steel column. Connections with anchors are set in concrete within the foundation. You can select anchor types M12 – M42 with steel grades of 4.6 – 10.9. The top and bottom sides of the anchors can be provided with round or angled sheets for better load distribution or anchorage. In addition, you can use rectangular or circular anchor heads with threads applied at the member ends.

The material and thickness of the grout layer, as well as the dimensions and material of the footing, can be set freely. Furthermore, you can define edge reinforcement of the footing. For a better transfer of shear forces, it is possible to arrange a shear key (cleat) on the bottom side of the base plate.

Shear forces are transferred by a cleat, anchors, or friction. You can combine the individual components.

After the calculation, RF-/JOINTS Steel - Column Base displays the following design results:

• Base plate bending
• Anchor tension and anchor shear force
• Shear key strength
• Concrete compression / failure of concrete edges
• Friction
• Welds
