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.
