Refuerzo en los nudos de las estructuras de hormigón armado con perfiles metálicos completamente embebidos

Abstract

Una estructura compuesta de Hormigón Armado con Acero, HAA, posee las propiedades resistentes del hormigón armado y la ductilidad del acero, por lo que mediante un diseño apropiado se puede conseguir una alta capacidad de resistencia sísmica. En la presente investigación se muestran los resultados y conclusiones obtenidos al analizar la resistencia y ductilidad de tres nudos diferentes ensayados con ciclos de carga y descarga crecientes hasta rotura, uno de Hormigón Armado, HA, otro de hormigón armado con la misma armadura estándar y con un perfil de acero estructural embebido, HAA, y un tercero de Hormigón Armado con la misma capacidad resistente de la sección de HAA. Se consigue dotar a las estructuras isostáticas e hiperestáticas de suficiente capacidad de aviso antes del agotamiento, de una gran capacidad de disipación de energía y de una protección adecuada frente al fuego.

A composite structure with steel reinforced concrete, SRC, has the strength properties of reinforced concrete and steel ductility, so that by appropriate design can achieve a high capacity for seismic resistance. The present investigation shows the results and conclusions obtained by analyzing the strength and ductility of three different nodes of a structural frame tested with increasing load and unload cycles, one of them with Reinforced Concrete, RC, another with steel reinforced concrete, SRC, and a third only reinforced concrete with the ultimate strength capacity of the section SRC. It manages to give hyperstatic and isostatic structures with sufficient capacity before exhaustion warning. It shows also a large energy dissipation ability and adequate protection against fire.
