The paper reports the results of the research activity aimed to define the physical-mechanics characteristics of structural elements made of wood-steel, and/or wood-steel-concrete, jointed by steel con¬nectors. The elements used for the tests are: glulam beams with two dif¬ferent dimensions (110x240x4000 mms and 110x140x4000 mms); steel flats 100x6x4000 mms with holes 20 mms arranged like "quinconce"; steel connectors like: flat with 6 mms thickness; 18; angular; polymeric synthetic binder with epoxy base bicomponent (Xepox 40.3/5). Shear tests have been made to define the capacity for deformation and the re¬sistance of the different steel connectors. Moreover, bending tests have been made with the aim to verify the effectiveness of the structural col¬laboration among wood-steel beam and concrete slab. The paper shows the different tests cycles and gives useful information about the possibil¬ity to use the tested structural systems not only for building new wood-steel-concrete floors but also for the recovery of existing solid wood floors.
