Estudio analítico-experimental del desempeño de un pórtico de hormigón armado con panel de relleno de bloque de baja resistencia, a través de un ensayo a carga lateral y modelo computacional

Abstract

The present work seeks to validate the model of a reinforced concrete portico with a filler panel proposed in the SeismoStruct program to predict the performance of this typology considering the specific characteristics of certain typical materials in the city of Quito. It is necessary to know the global inelastic behavior of the reinforced concrete portico with the influence of the filler panel, performing a computational model to know the nonlinear response by means of a monotonic pushover analysis, in addition to a cyclic lateral load test, and to compare the curve of Analytical capacity with the envelope capacity curve obtained experimentally with the purpose of validating the model. From the experimental hysteretic curve, characteristic properties of the system behavior were determined: failure modes, energy dissipation, stiffness degradation and equivalent viscous damping. The performance criteria are determined from the analytical capacity curve, allowing us to effectively identify the moments where the boundary states are reached and determine the structure's ductility. In order to determine the influence of the filler panel on the performance of the reinforced concrete portal, the analytical capacity curve of the portal with filler panel and without filler panel is analyzed.
