Shear resistance of concreted column
The distribution of shear forces along the column length is shown on the figure below. Following have have to be fulfilled:
The column has to be able to transfer maximum force above the foundation VEd
The column has to be able to transfer maximum shear force inside the foundation VEd,d
Shear distribution in detail
Where is: | Vwp,Rd |

Vpl,Rd |

Vwp,c,Rd |

The maximum shear force within the foundation VEd.d transferred by column web and concrete between flanges is given by the formula
The shear resistance of concrete between flanges Vwp,c,Rd is calculated in that way, that it corresponds to the shear capacity of concreted columns.
Where:
Compressive strut in concrete
