Experimental tests on wood-based in-plane strengthening solutions for the seismic retrofit of traditional timber floors

Traditional timber floors in masonry buildings are characterized by low in-plane stiffness and lack of effective connections to the main walls, so the structure seismic performance is negatively affected and a reinforcement is often needed. In-plane dry strengthening solutions for timber floors in existing masonry buildings are faced: OSB panels or CLT panels were connected to 12 traditional full-scale timber floors and tested under monotonic and cyclic loads. The results of the tested solutions are compared to the unreinforced floor results. The whole experiment supports the effectiveness of this kind of strengthening intervention.
