5. SEISMIC BEHAVIOUR OF RC COLUMNS EMBEDDING STEEL PROFILES region, even if some inconveniences occurred in the column length between the joint and the inflection point. It means that, a not accurate constructive process or the presence of not envisaged extra forces in the column may lead to an anticipated rupture in the absence of a full-length steel profile. Having had the chance to go further into detail, also looking at the inside behaviour of the beam-to-column joints, the mechanisms activated in the shear load transfer were determined. The evidence is that the investigated solution with the continuity plates (stiffeners) welded to the steel column at the joint region seems not to give a substantial contribution in helping the load transfer at the beam-to-column joint. Thus, as not influencing significantly the global response of the joint under study, their usage in practice could be neglected also because of their remarkable effect on the overall cost of the assemblage. Wishing to point out a commentary about the weak axis bending behaviour of the concrete frame structure, we underline the risk the building might run if the seismic wave comes along the minor axis bending and the columns were not specifically designed to withstand cyclic loads regardless the presence of the steel profile encased in the column. Finally, we can say that, at the moment, the new applications are concentrated on the improvement of the analytical models to evaluate the shear resistance at the connection by means of further numerical simulations by means of a FE program. It may be also interesting to produce a procedure in order to evaluate the behaviour of the one-sided type of joints starting from the conclusions drawn for the two-sided type of joints considered in this research thesis. 241
