For Eurocode 3 (ENV 1993-1-1:1992 and EN 1993-1-8:2005) and the French code CM66, the following column base types are available: 
- pinned column base 
 
- fixed column base 
 
- concrete column base 
 
Parameters defined for the pinned column base connection
- The set of forces considered during calculations of the connection: 
- axial force N (tensile or compressive) 
 
- shear force Qy and Qz 
 
- normal forces from the shear forces Qy and Qz 
 
  
- Connection parameters: 
- bar sections 
 
- stiffeners 
 
- column base plates 
 
- bearing 
 
- anchors 
 
- welds 
 
- wedge 
 
- concrete.
