Bending resistance of concreted column

These assumptions shall be fulfilled when designing detail with concreted detail:

Flange slenderness is limited by following expression:

The concreting height shall be within following limits:

The effective flange width beff is used for the design. This value take into the account the effect of inner edge of second flange for I and H profiles.

The analysis model uses following distribution of stresses in the detail:

Stress distribution valid till H= 2beff.

The horizontal forces Vh and Vd are given by expressions:

Horizontal equilibrium of forces:

Therefore:

Moment equilibrium for the column end:

The depth of concreting is calculated using following expression:
