Abstract:

The force transfer from steel to concrete without mechanical transfer devices in composite columns at points of load introduction is studied. A mechanism of force transfer and the factors influencing the transfer are identified by experimental and theoretical investigations. The important factors are quantified and incorporated into a simplified design equation. It is shown that the size of the steel section is the factor which has the most important influence on the magnitude of the shear resistance in the force transfer.
