In this paper, the concrete underneath the base plate together with the base plate is referred to as "component concrete in compression and base plate in bending" or in short "concrete in compression". Models are presented for the determination of the resistance and stiffness of this component. The models have been validated with tests. The paper also presents finite element calculations that provide additional validation. The predicted resistances according to ENV 1993-1-1 are conservative with a margin of 1.4 to 2.5 to the test results. The stiffness of the concrete in compression depends on the quality of the execution. In case of good workmanship, there is reasonable agreement between the measured and the predicted stiffness.

Key words: Base plate, concrete, analytical model, tests, finite element method
