[automatically translated] In the present work it refers to an experiment conducted on mixed trusses made using a steel trellis prepared in the factory, having as less current as a metallic plate and the upper current and bars wall rods from ca, then drowned in a concrete casting, thus obtaining a composite beam stainless-concrete. For the specificity of the type, the transmission of forces between the two materials is not comparable to that of traditionally designed composite beams nor to that of the RC beams The experimentation conducted through bending tests on four points had as its main purpose the evaluation of the length transfer beyond which the plate can be considered cooperative. Therefore, in addition to the relief of the answer in global terms (load-deflection) were carried out strain gauge measurements. On the location of the strain gauges and their reading is a particular focus in this work.
