Experimental Study of the Composite Timber- Concrete SBB Connection under Monotonic and Reversed-Cyclic Loadings

The present paper investigates the mechanical behavior of a novel dowel-type Timber-Concrete Composite system, namely SBB, under monotonic and reversed-cyclic loadings. This system consists of timber beams connected to a concrete slab using a dowel type connection. Because the structural behavior of timber-concrete composite slabs is mainly governed by the shear connection between concrete and timber, an extensive experimental program was carried out in order to assess its behavior under both monotonic (serviceability design) and cyclic loadings (seismic design) and to identify failure modes for each possible configuration. In order to fully characterize the load-slip behavior of the SBB connection under both monotonic and reversed cyclic loading, 24 Push-Out tests (12 under monotonic loading, 12 under reversed cyclic loading) were performed. The experimental program and the results (parameters and phenomenology) are discussed in this paper.
