Abstract

This research studies the non-linear behavior of a full-scale experimental joint (node), made up of three reinforced concrete elements, 1 column and 2 beams joined to a structural steel column at the upper level. In the numerical analysis, the union model was analyzed in the inelastic range, this model was elaborated with the finite elements program based on SeismoStruct fibers, to analyze in function of time, the tensile and compressive stresses in the confined and non-confined zones of the concrete column and in the longitudinal reinforcement steel, as well as the verification of the design of the base plate that joins the two columns. The results showed that the traction stresses in the unconfined zone exceeded the limit of concrete breakage, with cracking just below the lower edge of the beams; in the confined zone the traction stresses were much lower, with later cracking than in the unconfined zone. The concrete-column steel column joint behaved as a rigid node, so the elastic design was in accordance with the base plate calculation methodology for steel columns.
