Analisis del comportamiento estructural de nudos hibridos

Abstract

The basis of this work is broken down into several chapters in order to express in a pertinent way what the joints or knots in the structures are about, which must be a basic design concept, especially essential when executing the process of construction. For the definition of a referential framework that provides bases for the analysis of hybrid nodes, the design conception of homogeneous nodes of reinforced concrete and structural steel was taken as a guide, where basic theories of resistance, adhesion and stability were considered, allowing the formation of an analysis procedure for the study of hybrid nodes, where laws or constitutive models of the materials were also taken into account, among which are Mander's confined concrete and the trilinear or complete curve for structural steel, with the purpose of obtain the curvature moments of the section under study. The study is based on assessing the structural behavior of a hybrid node composed of a main concrete beam crossed by a secondary metal beam, in order to measure the influence that the steel beam has on the concrete beam, based on the criterion of that the secondary beam affects the resistant capacity of the main beam. With this, it was visualized that the behavior and resistance capacity of the main beam were only affected if the secondary steel beam invaded the compression block.
