 Summary:
 Opposite to steel-concrete composite structures that generally consider the rigid connections, the values for "slip" modulus of timber connectors are of essential interest in modeling the wood-concrete composite beams with controlled contact deformations. SRPS regulative doesn't give any recommendation for connector slip characteristics in wood-concrete systems, so the values proposed in EC5 and accompanying studies have to be adopted in practical design using the commercial software. Trough one numerical example and relevant discussion, the paper presents possibilities of practical "slip" modulus estimation for dowel type studs, in cases of existence and non-existence of formwork. The modeling and computational results are discussed in order to show the limitation of EC5 recommendations, as well as possibilities of practical "slip" modulus estimation and it adoption in design using domestic commercial software.
