Design of Hinged and Restrained Column Bases

The RF-/JOINTS Steel - Column Base add‑on module designs footings of hinged and restrained column bases according to:

EN 1993‑1‑8 (including National Annexes)

Features
Hinged Column Footing category provides four different base plate connections:
- Simple column base
- Tapered column base
- Column base plate for rectangular hollow sections
- Column base plate for circular hollow sections
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 on both sides of column and web members
- Bucket footing
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 anchors types M12 – M42 with steel grades of 4.6 – 10.9. The top and bottom side of anchors can be provided with round or angled sheets for a better load distribution or anchorage. In addition, you can use rectangular or circular anchor heads with threads applied at the member ends.

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 by friction. You can combine the individual components.
Input

After selecting a joint type and a design standard in the first input window, you can define nodes imported from RFEM/RSTAB to be designed on footing anchorage.

Optionally, you can define the column cross-section and material manually. The other input windows include footing parameters such as a base plate, anchors, shear keys, and stiffeners. Loads are imported from RFEM/RSTAB or entered manually in the case of user-defined joint definition.
Design
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
Results

At first, the governing joint designs are arranged in groups and displayed with the basic geometry of the joint in the first result window. In the other result windows, you can see all fundamental design details such as the load-carrying capacity of anchors, stresses in welds, and others.

Dimensions, material properties, and welds important for the connection construction are displayed immediately and can be printed directly. It is possible to visualize the connections in RF-/JOINTS Steel - Column Base or in the RFEM/RSTAB model.

All graphics can be included in the RFEM/RSTAB printout report or printed directly. Result graphics to scale provide the option of an optimal visual check right from the design phase.
