Effect of foundation flexibility on ductility reduction factors for R/C stack-like structures

Earthquake Engineering and Engineering Vibration, 2011
The most important parameter used to determine force reduction factors in force-based design procedures adopted in the current seismic codes is the structural ductility. For a structure supported on a flexible foundation, the ductility factor could be affected by foundation compliances.

The ductility-based strength reduction factor for the mainshock–aftershock sequence-type ground motions

Bulletin of Earthquake Engineering, 2015
This manuscript investigates the strength reduction factor of single degree of freedom system with constant ductility performance subjected to the mainshock–aftershock sequence-type ground motions. The recorded and artificial sequence-type ground motions are used. The aftershock ground motions in sequence are scaled to have different relative intensity

Evaluation of Response Reduction Factor for RCC Moment Resisting Frame with Ductile Shear Wall

2020
Most of the buildings are irregular and their behavior during the event of earthquake is significantly different than that of regular buildings. The actual base shear which act on the building is much higher than the designed base shear. That is why it is uneconomical to design the building for the actual base shear. The building is expected to undergo

Modification of Ductility Reduction Factor for Strength Eccentric Structures Subjected to Pulse-Like Ground Motions

Journal of Earthquake Engineering, 2015
This article investigates the ductility reduction factors for RC eccentric frame structures subjected to pulse-like ground motions. The structural models are with the strength eccentricities which are much disadvantageous than the stiffness eccentricities during the inelastic response range.

An evaluation of the ductility reduction factor q in the 1976 regulations for the federal district of mexico

Earthquake Engineering & Structural Dynamics, 1989
AbstractThe reduction of the spectral accelerations to account for inelastic response of structures as given by the 1976 Regulations for the Federal District of Mexico is evaluated relative to the records obtained at the Secretaria de Communicaciones y Transportes (SCT) during the September 19, 1985 Mexico earthquake.

DUCTILITY DEMANDS CONTROL UNDER REPEATED EARTHQUAKES USING APPROPRIATE FORCE REDUCTION FACTORS

Journal of Earthquake and Tsunami, 2010
This paper develops a new procedure for the ductility demands control of single-degree-of freedom (SDOF) systems under multiple earthquakes. According to the proposed method, this objective can be achieved using appropriate force reduction (R) factors. In this way, the total ductility demands, and therefore the cumulative damage levels, are absolutely
