For the design of timber-concrete composite (TCC) elements with notches, the slip modulus Kser represents an important property of the connection. In this paper available research results were gathered and further experimental tests were carried out in order to define the slip modulus of a notched connection. Therefore experimental push-out and beam tests have been conducted on timber-concrete composite specimens. Test series included specimens with and without screws in the notches. Also the failure mode of the connection as well as the application of the slipmodulus (obtained from the push-out tests) in TCC elements have been investigated.
