Abstract

The stiffening and strengthening of wooden floors with a thin collaborating concrete slab is a recent technique, which appears particularly suitable for restoration of ancient buildings. In this experimental research work a simple kind of connection is studied, suitable for practice, using materials that are normally available in the ordinary restoration yard. Tests are carried out both for studying the global behaviour of the composite beams and the local behaviour of the connections. They are conducted on two different composite beams, one with the concrete slab in direct contact with the wood beam, the other with interposed planks. Stud connectors are used which are obtained by ordinary smooth steel bars simply forced into calibrated
