Experimental assessment and modelling of in-plane behaviour of timber floors

In the paper, the assessment of the in-plane behavior of timber floor samples is proposed by experimental laboratory tests, aimed at characterizing the basic properties of simple construction floor typologies, common in existing masonry buildings, for the proper selection of structural improvement solutions. On the basis of the analysis of the testing procedures and systems proposed in literature, a specific set-up has been designed and realized, in order to minimize undesirable and/or uncertain effects, able to simulate both monotonic and cyclic shear behaviour. The first experimental results on unreinforced floors are discussed, together with the calibration of a preliminary FE model.
