Estudio experimental de columnas tubulares en lámina delgada de acero rellenas de hormigón, sometidas a flexión

Abstract

At the moment in the country, use of the steel has been increased on construction, especially in structures of significant magnitudes. For this reason, the study of steel, gained importance, and in this document is intended to generate experimental information of composite sections, so called to tubular sections of structural steel filled with concrete. The composite sections with respect to another constructive system have the advantage of a higher capacity of resistance, collaborating with less weight to the structure. The rules in which the composite sections are taken into account are the American AISC codes and the Euro code. In the section corresponding to the “Buckling”, the broad-thickness relationships that must be fulfilled are contemplated to avoid failures due to this condition. For this study, we proceeded to the construction of 8 specimens, of a standard height, and square geometry, in steel A50. The sections were designed to exceed the limits established by the codes, in order to obtain slender elements and be tested in flexion.
