Abstract: Corroded steel bars frequently exist in concrete structures under chloride exposure conditions. Tensile behaviors of corroded steel bars at high temperatures are important in the fire-resistance evaluation of corroded ...

Abstract: The purpose of this paper is to develop mesoscale models for predicting the diffusivity of cement mortar by numerical and analytical methods. The interfacial transition zone (ITZ) volume fraction was calculated by a ...

Abstract: This paper presents an experimental investigation of the degradation of the mechanical behavior of corroded prestressing wires under high-cycle fatigue loading. To quantify the influence of corrosion degree, stress range, ...

Abstract: An understanding of how corrosion affects fatigue behavior of reinforced concrete (RC) structures is essential for lifetime-oriented maintenance and design of existing bridges. This paper covers an experimental investigation ...

Abstract: This paper presents the development of a probabilistic model for the cross-sectional area of corroded reinforcing steel bars (rebars), in order to assess the time-dependent reliability of corroded reinforced concrete (RC) ...

Abstract: This paper presents the results of a study on the mechanical behavior of concrete columns strengthened with fiber-reinforced polymer (FRP) and subjected to concentric and eccentric compression loading. A numerical analysis ...

Abstract: Seven beams, four columns, and two single-bay one-story frames have been recently designed in order to create different crack patterns and to investigate heat propagation in cracked reinforced concrete structures. Commercially ...

Abstract: Stirrups in RC beams are more vulnerable to corrosion than longitudinal steel bars due to the thinner concrete cover, and the shear behavior may deteriorate faster than the flexural behavior under fatigue loading. An ...

Abstract: This paper presents the results of a study on the compressive behavior of timber columns with longitudinal cracks. Material property tests and full-scale compression tests were conducted to investigate the failure modes ...
