Abstract: Overload attributable to increased vehicle loads is becoming an increasingly serious issue in highway transportation. Overload results in damages to bridge structures, degradation of their load-carrying capacities, and ...

Abstract: This paper presents the results of an experimental study investigating the mechanical behavior of corroded beams strengthened by three different strengthening schemes, and the influence of further corrosion on the structural ...

Abstract: Concrete cracking induced by strand corrosion can degrade bond strength and lead to prestress loss. A novel model is proposed to predict corrosion-induced prestress loss in pretensioned concrete structures. The coupling ...

Abstract: The coupled effect of corrosion and fatigue deteriorates the performance of reinforced concrete (RC) structures. This paper proposes a novel framework for the probabilistic life prediction of aging RC structures under ...

Abstract: This paper investigated the corrosion fatigue crack propagation mechanism of high-strength steel bar HRB400 in various corrosive environments. Fatigue crack growth (FCG) tests were conducted under different fatigue loading ...

Abstract: Fatigue changes the mechanical behavior of reinforcing bars, significantly reducing the performance of aging concrete structures. This study performed a fatigue loading test on post-tensioned prestressed concrete (PC) beams ...

Abstract: Fatigue damage has become one of the key issues affecting the service safety of steel bridges with the continuous increase of vehicle load and traffic volume. In this paper, fatigue crack growth (FCG) tests were performed ...

Abstract: Bridge steel, frequently employed in cross-sea bridge construction, exhibits excellent weldability, superior strength, and toughness. The service life and stability of steel structures are influenced by the presence of ...

Abstract: The corrosion-induced bond degradation between corroded steel strands and concrete is investigated in the present study. Ten pull-out specimens with different corrosion levels were tested to study corrosion’s effects on ...

Abstract: An analytical model is proposed in this paper to evaluate the residual flexural strength for corroded RC beams. The steel slipping caused by bond degradation is included in the proposed model. Various failure modes of beams ...
