| Resumo: | This research analyzes the solution of reinforced concrete joints reinforced with steel sections, known as steel reinforced concrete (SRC). The aim is to verify the improvement of the ductile characteristics of steel reinforced concrete structures compared to conventional reinforced concrete structures. Another objective is to better understand the experimental behavior and thus be able to perform numerical simulations adjusted with the experimental ones. In addition, the behavior of reinforced concrete structures in all the bars with steel sections is compared with others in which only the joints are reinforced to obtain more efficient and economical structures. All these objectives have the main purpose of improving the behavior of structures against seismic loads. Five specimens of concrete joints with reinforced with steel were tested with cyclic loads to analyze their behavior. The strength superposition method can predict the shear strength. The results obtained confirm the greater capacity of absorption of energy of the structures with sections of steel embedded compared with the structures of conventional reinforced concrete, with greater ductility when facing large displacements. © 2019 by the authors. |
