Connections of steel columns to concrete foundations may be loaded by combinations of
normal force, bending moment and shear force. Shear force will primarily be transmitted by
friction between the base plate and the grout layer to the concrete foundation. If the compression force is small, or if tension force is present, as may occur in slender high rise structures like towers and masts, the friction will be small or absent. Then, the anchor bolts will be loaded by shear force and bending moment. At the Stevin Laboratory of Delft University of Technology, experimental and theoretical research has been carried out on column bases loaded by combinations of shear force and tension force.
In the paper, the main results of this research programme are summarised. The test results are presented and the analytical model that was developed to describe the load deformation
behaviour.
