Abstract
In this study,
residual displacement demands are investigated for SDOF systems with period
range of 0.1-3.0 s for near-field and far-field ground motions. The effects of
stiffness degradation and post yield stiffness ratio on residual displacements
are investigated. The modified-Clough model is used to represent structures
that exhibit significant stiffness degradation when subjected to reverse cyclic
loading. The elastoplastic model is used to represent non-degrading structures.
For inelastic time history analyses, Newmark’s step by step time integration method
was adapted in an in-house computer program. Based on time history analyses, a
new simple equation is proposed for residual displacement demand of a system as
a function of structural period (T), ductility (µ), strain hardening ratio (α)
and spectral displacement (Sd).
