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

  • The shear resistance of concreted steel column

Vpl,Rd

  • The shear resistance of steel column

Vwp,c,Rd

  • The shear resistance of concrete between flanges and column web

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
