Non-linear 3D finite element analysis of the anchorage zones of pretensioned concrete girders and experimental verification

open access: yes, 2018
This paper focuses on the modelling of the anchorage zone of a pretensioned girder. The finite element software Abaqus was used to create a 3D non-linear finite element model (FEM). This analysis was performed on a full-scale pretensioned girder with end

Long‐Term Stress Adaptation as a Highly‐Conserved Key Factor in Yeast Aging

open access: yesAging Cell, Volume 25, Issue 5, May 2026.
This study shows that long‐term, but not short‐term, stress exposure triggers molecular changes in yeast that mirror established hallmarks of aging, including altered proteostasis, epigenetic shifts, and reduced lifespan. These changes are reversible upon stress removal, and the genes involved are conserved across all domains of life. ABSTRACT Aging is

Effect of the Nonprestressed/Prestressed BFRP Bar on Flexural Performance of the Bamboo Beam

open access: yesAdvances in Polymer Technology, 2019
Until now, the systematical and comprehensive strengthening techniques have not been formed for the bamboo structure. Under such background, this paper aims to explore the effects of the application of the nonprestressed and prestressed basalt fiber ...

Top Bar Effects in Prestressed Concrete Piles [PDF]

open access: yes, 2002
The top bar effect in reinforced concrete is a widely recognized phenomenon. Currently, the ACI Building Code prescribes a 30% increase in the development length of top cast reinforcing bars.

Internal and External Prestress Reinforcement Technology for Prestressed Continuous Box Girder

open access: yesZhongwai Gonglu
A prestressed concrete cast-in-situ continuous box girder bridge faces transverse cracking of the bottom plate of the second span and the overall stiffness decline. To address this issue, this paper analyzed the causes of the damage.

Hyperelastic cloaking theory: Transformation elasticity with pre-stressed solids

open access: yes, 2012
Transformation elasticity, by analogy with transformation acoustics and optics, converts material domains without altering wave properties, thereby enabling cloaking and related effects.

Experimental and Theoretical Study on Anchorage Loss of Prestressed CFRP-Reinforced Concrete Beams

open access: yesApplied Sciences
To investigate the anchorage loss mechanism of externally prestressed CFRP tendons in concrete beams, this study introduces a novel theoretical calculation system (TCS) developed through both the finite element method (FEM) and experimental validation ...

Excessive Strand End Slip in Prestressed Piles [PDF]

open access: yes, 2000
This paper presents the results of a research project that investigated excessive strand end slip observed recently in some prestressed piles. From measurements taken in the field, it is apparent that the problem o excessive initial strand slip is ...
