ANALISI SPERIMENTALE DEL COMPORTAMENTO CICLICO DI NODI DI TRAVI SER E PILASTRI IN C.A.
Results of experimental investigation on cyclic behavior of beam-column joints made up of hybrid steel trussed concrete beams connected to reinforced concrete columns are presented. Specimens are representative of joints in framed structures subjected to seismic actions designed according to current Italian technical standard codes. The aim of the experimental testing was to verify strength capacity and ductility of the connection, focusing both the global behavior and the force transmission mechanisms between steel truss and concrete in the region close to the beam-column joint.
ANALISI TEORICO-SPERIMENTALE DEL COMPORTAMENTO A TAGLIO DI TRAVI PREFABBRICATE RETICOLARI MISTE
An experimental campaign of three-point bending tests on specimens of Hybrid Steel Trussed Concrete Beams (HSTCBs) is presented. The scope of the experiments is the evaluation of the shear strength in the structural typology object of study. Two series of specimens are tested, subjected to positive and negative bending moment, respectively, with the aim to reproduce, in the first case, the condition in the midspan of a beam belonging to a framed structure and, in the second case, the behavior of the beam next to the column where the sign of the bending moment is reversed. The obtained experimental results are interpreted by means of an analytical model for the prediction of the shear resist…
