Desarrollo de programas para el análisis de estructuras aporticadas usando el método de Diseño Basado en Desplazamientos para el software “Diseniosm”.

Abstract

Although the Force – Based Design is generally used to obtain the base shear force to be applied to a structure, it has been determined that this procedure has some deficiencies, which have caused that the designed structures have a variable vulnerability to earthquakes. For this reason, the Displacement – Based Design has been developed in recent years, which overcomes the deficiencies of the Force – Based Design. From this, a program is developed for the analysis of frame structures using the Displacement – Based Design procedure. With this program is possible to obtain: the forces in the elements, the design of the reinforced concrete elements, and the strains in the plastic hinges. Then, two reinforced concrete structures, one regular and the other irregular, are proposed and designed using the Force – Based Design and the Displacement – Based Design. Finally, nonlinear time – history analysis is used to compare the displacement profiles, drifts and the performance achieved by the designed structures.
