Alternative procedure to determine the response reduction factor for ductile rc framed buildings
The seismic design is based on the results of the structures elastic analysis, even though now days the nonlinear analysis is increasingly accessible. To perform the seismic analysis of structures that are modeled with elastic behavior, but known to venture into the plastic behavior, the standards e...

El diseño sismorresistente vigente se fundamenta en los resultados del análisis elástico de las estructuras, a pesar de que en la actualidad el análisis no lineal es cada vez más asequible. Para realizar el análisis sísmico de estructuras que se modelan con comportamiento elástico, pero que se conoce incursionarán en comportamiento plástico, las normas prescriben la reducción de los espectros elásticos de diseño mediante el uso de factores de reducción de respuesta, formulados éstos esencialmente sobre la base del juicio ingenieril. En este trabajo se propone una metodología para obtener los factores de reducción de respuesta, con base en los resultados del análisis no lineal de la respuesta del suelo y de sistemas estructurales de un grado de libertad, conjuntamente con la respuesta no lineal de sistemas estructurales de múltiples grados de libertad aporticadas de concreto armado, para las formas espectrales de Venezuela. Los resultados obtenidos son mayores que los actuales valores de los factores de reducción de respuesta contemplados en la norma sismorresistente venezolana, lo cual puede conducir favorablemente a un diseño por desplazamientos y no por resistencia.

The seismic design is based on the results of the structures elastic analysis, even though now days the nonlinear analysis is increasingly accessible. To perform the seismic analysis of structures that are modeled with elastic behavior, but known to venture into the plastic behavior, the standards establish the reduction of the elastic design spectra by the use of reduction factors, formulated essentially on the basis of the engineering judgment. This paper proposes a strategy to obtain response reduction factors, based on the results of non-linear analysis of soil response and structural systems with a degree of freedom, along with the non-linear response of multiple grade of freedom framed structural systems by armed concrete, for the specific spectra of Venezuela. The results of response reductions factors were greater than the current values of response reduction prescribed by the Venezuelan seismic code, which can favorably lead to a displacement-based design instead strength-based design.
