Residual displacements of RC structures as SDOF systems
Earthquake Engineering and Structural Dynamics, 2015SummaryResidual displacements are sensitive to ground motion details, hence more random than peak inelastic displacements. Among the factors with systematic impact on residual displacements, the post‐yield‐stiffness‐ratio has been studied thoroughly; its effects are not investigated further. Concerning another important factor, the hysteresis law, past

Earthquake Engineering and Engineering Vibration, 2020
Structures undergoing inelastic displacements during earthquake ground motions are known to sustain some amount of residual displacements, which may make them unusable or unsafe. In this study an attempt is made to estimate residual displacements for elastic-perfectly-plastic single-degree-of-freedom oscillators with a given lateral strength ratio.

POST-EARTHQUAKE RESIDUAL DISPLACEMENTS OF BILINEAR OSCILLATORS
Earthquake Engineering and Structural Dynamics, 1997Structures subjected to large inelastic deformations during violent ground shaking do not always return to their initial ‘at-rest’ position but may have residual displacements. Even if collapse does not occur, large residual displacements may render them unusable or irreparable. In order to investigate the likely magnitude of residual displacement many

Study on normalization of residual displacements for single‐degree‐of‐freedom systems
Earthquake Spectra, 2021Residual displacement spectrum is one of the most important means to predict the permanent deformation of structures after the earthquake, and various normalizations of residual displacements have generally been used for construction of the spectrum ...

Residual displacements for non-degrading bilinear oscillators under seismic actions
Mechanics Research Communications, 2021This work aims to provide a relationship to assess the residual displacements for one-storey buildings standing in seismic-prone areas. The maximum residual displacement that a structure can possibly sustain is clearly identified by means of its ...

Investigation on residual displacements for SDOF systems with various initial viscous damping models
Structures, 2020Nonlinear time history analysis (NTHA) is widely used in estimation of post-earthquake residual displacement demands. However, the choice of initial viscous damping models in NTHA has attracted insufficient attention in study of residual displacements ...

Normalized Residual Displacements for Bilinear and Pinching Oscillators
Journal of Structural Engineering, 2020A correct estimation of residual displacements due to an earthquake event is crucial in satisfying the limit state of repairability after the event and for assessing the safety of structure...

Estimating Residual Seismic Displacements for Bilinear Oscillators
Practice Periodical on Structural Design and Construction, 2016AbstractAn important consideration in the design of structures for seismic effects is residual displacement. However, few design specifications have residual displacement criteria. As performance-based design gains popularity, the need arises to estimate residual displacements in structures from strong ground shaking.

On the Inversion of Residual Stresses From Surface Displacements
Journal of Applied Mechanics, Transactions ASME, 1989When plastic damage regions are accumulated in a material, there exist residual displacements on the surface of the material after all the loadings are removed. The residual displacements are defined as the difference between before and after loading, and can be measured experimentally without destruction of the material.
