Hey, I am doing a dissertation on semi-rigid steel beams with cross laminated timber floors. The timber floor can act as either a non-composite or composite structure with regard to the semi-rigid steel beam connection. What is the design procedure for the case in which the steel beam (with semi-rigid connection) acts along with the timber floor in composite construction?
Hey, there is a simplified method in Eurocode 5 Annex B derived by Möhler and Stüssi how to calculate semi-rigid jointed beams. The slip modulus K is parameter which discribes the stiffness of the connection. It is the ratio between force and shear displacement.

Nirmala's references are excellent.
The main issue is the degree of composite action (or if you prefer, the degree of slip). For a semi-rigid connection, the degree of slip will be governing. You will have to determine the degree of slip that your connection method will produce. You can model this in a finite element program using flexible connectors between the beam and the deck.
If you are considering repeated loads, including earthquake action, you will also need to consider the fatigue of the connection.
Good question… Please check references below.. hope it will be helpful for you…

Various materials have been used as connectors, including hardwood, steel coach screws, embedded steel plates and frp dowels. You need to check the literature for the performance of the dowels.- Badges
