Análisis de una Placa Base de Unión entre Columna de Concreto-columna de Acero en el Rango no Lineal

In this work, the behavior in the linear and nonlinear range of a joint (beam-column joint) was studied in a full-scale specimen, consisting of a concrete column connected to two concrete beams by a monolithic casting; the concrete column was connected through a steel base plate to a HEA160 steel column subjected to cyclic loads during a period of 5,000 s, thus obtaining its hysteretic behavior curve. A mathematical model was created in the ABAQUS CAE program in order to verify that the design of the specimen joint complied with the normative requirements for the design of base plates, based on concrete crushing and plate thickness. The bolts were checked for their resistance to shear forces, tensile deformation, verification by tensile cone in the concrete and tensile stresses within the cracked zone, with the result that the failure was caused by cracking of the reinforced concrete.
