Prediction of residual displacement ratios for simple structures built on soft-soil sites of Mexico City

Soil Dynamics and Earthquake Engineering, 2019
This short communication discusses the prediction of residual displacement demands through residual ratios (i.e., the ratio of residual displacement demand to the maximum displacement demand) for single-degree-of-freedom (SDOF) systems subjected to ...

POST-EARTHQUAKE RESIDUAL DISPLACEMENTS OF BILINEAR OSCILLATORS

Earthquake Engineering & Structural Dynamics, 1997
Structures 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

Probabilistic Characteristics of Residual Displacements of SDOF Systems

Applied Mechanics and Materials, 2013
Probabilistic residual displacement analysis plays an important role in determination of technical or economical feasibility of repairing the damaged emgineering structures after an earthquake. Probabilistic characteristics of residual displacements of SDOF systems were quantificationally investigated in this study through a comprehensive statistical ...

Mechanisms of Residual Oil Displacement by Steam Injection

SPE Reservoir Engineering, 1987
SummaryIn an attempt to isolate various thermal and hydrodynamic mechanisms, a model of one-dimensional (1D) steam displacement of residual oil has been developed. The quasisteady model considers capillary pressure gradients and gravity forces during the simultaneous flow of oil, water, and steam to be the dominant factors in oil-bank mobilization.

Simple method to estimate residual displacement in concrete bridge columns under near-fault earthquake motions

Engineering structures, 2018
The most direct method to estimate lateral residual displacement under earthquake loading is nonlinear response history analysis, which is time consuming and complicated. A simple method is highly desired to estimate residual displacement.

Acute and residual neuromuscular effects of displacement in indirect vibratory stimulation

Journal of Electromyography and Kinesiology, 2021
The aim of this study was to evaluate the effect of indirect vibratory stimulation on different magnitudes of displacement on acute and residual neuromuscular responses. Fifteen healthy volunteers were randomly submitted to 3 experimental sessions, with intervals of 5 to 7 days (5 maximal voluntary contractions - MVC, 12 s of duration each and 5 min of

Normalized Residual Displacements for Bilinear and Pinching Oscillators

Journal of Structural Engineering, 2020
AbstractA 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...

Residual displacements of RC structures as SDOF systems

Earthquake Engineering & Structural Dynamics, 2014
SummaryResidual 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

Interfacial effects in the entrapment and displacement of residual oil

AIChE Journal, 1974
AbstractQualitiative theories are developed to explain the roles of surface tension and the two surface viscosities during the entrapment of residual oil by water and during the subsequent displacement of residual oil by surfactant solutions. The results are in agreement with available experimental data concerning the effects to be observed as the oil ...

Displacement discontinuity as a result of residual stress relief

2017 8th International Conference on Mechanical and Aerospace Engineering (ICMAE), 2017
The paper focuses on the problem of crack formation in an infinite strip with free sides as a result of residual stress relief. The formulas for residual stresses and for the corresponding displacements have the form of series in Papkovich-Fadle eigenfunctions.
