This study presents a numerical model to characterize the fracture process of reinforced concrete (RC) beam strengthened with fiber-reinforced polymer (FRP) in detail. A based on application cohesive elements was developed. Mixed-mode constitutive models were proposed mechanical behavior FRP–concrete interface, potential surfaces, and rebar–concrete interface. The normal separation interface its coupling effect shear considered model. In addition, friction explicitly Three different typical...
High-voltage operation is essential for the energy and power densities of battery cathode materials, but its stabilization remains a universal challenge. To date, degradation origin has been mostly attributed to cycling-initiated structural deformation while effect native crystallographic defects induced during sophisticated synthesis process significantly overlooked. Here, using in situ synchrotron X-ray probes advanced transmission electron microscopy probe solid-state charge/discharge...
This paper reports on a series of four-point bending experiments to investigate the shear capacity reinforced concrete (RC) beams strengthened with externally bonded basalt fiber–reinforced polymer (BFRP) sheets. The experimental results show that BFRP sheets can significantly increase RC beams' and ductility. To analyze fracture mechanical behaviors sheet–strengthened beams, three-dimensional (3D) finite-element model (FEM) based application cohesive elements was developed. Mixed-mode...
The increasing prevalence of simply supported bridges in high-speed railway (HSR) lines has raised concerns about the safety trains crossing these during an earthquake. As are typically continuous and long, it is essential to consider effects traveling seismic waves on random vibration train-bridge coupled (TBC) system. To address this issue, new point estimate method (NPEM) used analyze dynamic response parametric sensitivity a three-dimensional TBC system subjected non-uniform ground...
Engineered Cementitious Composite (ECC) material, as a hybrid also has uncertainties. In addition, the shear failure mechanism of reinforced ECC (R-ECC) member is different from that ordinary concrete (RC) member, and new material partial factor needed. This paper conducted experiments for statistical mechanics strength. The test data 36 R-ECC members were collected, four representative bearing capacity calculation models collected assessed. Then, limit state function beams was derived,...
This paper presents a new method for analyzing the dynamic behavior of train–bridge systems with random rail irregularity aimed at its simplicity, efficiency and accuracy. A vertical system is considered, in which bridge regarded as series simply supported beams, train multibody suspensions. The Karhunen–Loéve expansion (KLE) used to simulate stochastic irregularities, mean standard deviation response are calculated by point estimate (PEM), based on Gaussian integration dimension reduction...
The extension of high-speed railway construction to earthquake-prone regions has significantly increased the probability trains encountering an earthquake while running on a bridge. Therefore, it is urgent explore applicability additional static quality method (ASQM) train load simulation specified in Code for seismic design engineering. Based comprehensively considering uncertainty ground motions, this paper builds spatial analysis models train–track–bridge systems based ASQM and moving...
Rail irregularity presents a major threat to the high-speed train (HST) safety on rail (HSR) bridge. Lateral bridge deformation has significant impact geometric parameters of rail. In this paper, influence lateral operation HSR is investigated. Variational calculus employed establish analytical mapping between and deformation. By superimposing mapped initial random irregularity, composed unevenness under obtained. Thereafter, by adopting dynamical model train-track-bridge coupling system...
Alloy-based materials are promising anodes for rechargeable batteries because of their higher theoretical capacities in comparison to graphite. Unfortunately, the huge volume changes during cycling cause serious structural degradation and undesired parasitic reactions with electrolytes, resulting fragile solid-electrolyte interphase formation capacity decay. This work proposes mitigate suppress interfacial reactivity Ge without sacrificing Li+ transport, through situ construction an...
After an earthquake, a track-bridge system may suffer damage and residual deformation, posing threat for trains passing over bridge. However, since railway transportation is important channel disaster relief, the timely passage of great significance materials personnel. In past, subjective experience-based judgments were made on whether train can pass earthquake-damaged bridge, no relevant numerical calculations carried out. Therefore, strategy evaluation performance when existing bridges...
Background The 10-item Perceived Stress Scale (PSS-10) is a widely used measure of perceived stress that has been validated in various populations, yet with inconsistent results on its factor structure. present study examines the reliability and validity PSS-10 population not previously examined: Chinese family caregivers persons schizophrenia, focus analysis. Methods A sample 449 schizophrenia was recruited for psychometric testing scale. structure tested by randomly dividing into two...
