Research and Application of a Seismic Damage Classification Method of Concrete Gravity Dams Using Displacement in the Crest

Applied Sciences, 2020
Concrete gravity dams are one of the most common water retention structures, some of which are located in seismically active regions. Determination of damage level after earthquakes plays an important role in assessing the safety behavior of concrete ...

Prediction of residual stress using explicit finite element method [PDF]

Journal of Mechanical Engineering and Sciences, 2015
This paper presents the residual stress behaviour under various values of friction coefficients and scratching displacement amplitudes. The investigation is based on numerical solution using explicit finite element method in quasi-static condition.

Condition assessment of concrete piers subjected to impact load using fiber optic sensing

Case Studies in Construction Materials, 2022
A novel strategy for condition assessment of concrete piers subjected to impact load is presented in this article. The method of estimating residual displacement (lateral displacement and rotation angle) of concrete piers using long-gauge fiber optic ...

Displacement response estimation of a cable-stayed bridge subjected to various loading conditions with one-dimensional residual convolutional autoencoder method

Structural Health Monitoring, 2022
Displacement is an essential indicator of the functioning and safety of long-span cable-supported bridges under operational conditions. However, displacement estimation is challenging as these bridges are simultaneously subjected to various loading ...

Residual oil evolution based on displacement characteristic curve

International Journal of Mining Science and Technology, 2020
The purpose of this study was to determine the displacement and dynamic distribution characteristics of the remaining oil in the two development stages of water flooding and subsequent alkaline surfactant polymer (ASP) flooding. The well pattern types in

Thickness of residual wetting film in liquid-liquid displacement

Physical Review E, 2011
Core-annular flow is common in nature, representing, for example, how streams of oil, surrounded by water, move in petroleum reservoirs. Oil, typically a nonwetting fluid, tends to occupy the middle (core) part of a channel, while water forms a surrounding wall-wetting film. What is the thickness of the wetting film?

STRUCTURAL SHAKEDOWN: A NEW METHODOLOGY FOR ESTIMATING THE RESIDUAL DISPLACEMENTS

JOURNAL OF CIVIL ENGINEERING AND MANAGEMENT, 2016
A vector of residual forces of the ideally elastic-plastic structure at shakedown is obtained by solving the static analysis problem. A unique distribution of the residual forces is determined if the analysis is based on the minimum complementary deformation energy principle.

Normalized Residual Displacements for Single-Degree-of-Freedom Systems Subjected to Mainshock–Aftershock Sequences

Applied Sciences
Post-earthquake structural rehabilitation faces critical challenges from aftershock-induced cumulative damage, particularly through residual displacement accumulation that compromises structural realignment feasibility. While residual displacements serve

Investigation of the Water-Invasion Gas Efficiency in the Kela-2 Gas Field Using Multiple Experiments

Energies, 2023
Although improving the recovery of water-invaded gas reservoirs has been extensively studied in the natural gas industry, the nature of the efficiency of water-invaded gas recovery remains uncertain. Low-field nuclear magnetic resonance (NMR) can be used
