Estimating Residual Seismic Displacements for Bilinear Oscillators

Practice Periodical on Structural Design and Construction, 2016
AbstractAn 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.

Interfacial effects in the displacement of residual oil by foam

AIChE Journal, 1979
AbstractA qualitative theory is developed to explain the roles of surface tension and the two surface viscosities in the displacement of foams through porous media. There is a critical value of the surface tension above which a foam cannot be displaced under a given pressure gradient.

On the Inversion of Residual Stresses From Surface Displacements

Journal of Applied Mechanics, 1989
When 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.

The Effects of Residual Displacement on Gap Damper Performance

2014
Previous studies on base isolated systems have shown susceptibility to large displacements at the base level, leading to pounding between structure and perimeter moat wall during a maximum considered earthquake. Undesirable pounding can lead to very high acceleration in the superstructure.

Prediction of Residual Displacement of SDOF System from its Peak Inelastic Displacement

Applied Mechanics and Materials, 2013
Residual displacement is an important measure of post-earthquake functionality of engineering structures. Empirical equations for prediction of residual displacement of SDOF system from its peak inelastic displacement were proposed through a comprehensive statistical analysis. An inelastic seismic analysis model including the P-Δ effect was employed to

Residual stress evaluation using shearography with large shear displacements

Second International Conference on Photomechanics and Speckle Metrology: Speckle Techniques, Birefringence Methods, and Applications to Solid Mechanics; Moiré Techniques, Holographic Interferometry, Optical NDT, and Applications to Fluid Mechanics, 1991
A newly developed optical method for the qualitative and quantitative evaluation of residual and live-load stresses is presented. The method utilizes shearography employing a large angle shearing prism which results in large shear displacements. The large angle shearing prism allows the surface speckle pattern to be referenced and mapped onto a remote,
