Design Spectra for Degrading Systems
Publication: Journal of Structural Engineering
Volume 111, Issue 12
Abstract
The effect of stiffness or strength degradation, or both, under cyclic loading on the seismic response of single‐degree‐of‐freedom inelastic systems with 5% initial damping is investigated. Rules are proposed to construct inelastic design spectra for these systems (typical of reinforced concrete construction) as a function of the desired displacement (or ductility) ratio. These rules complement those used at present based on the response of simple elasto‐plastic systems without any degradation.
