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:
