Abstract: The bond behavior between a plain bar and concrete has received more attention in recent years because of its importance in the assessment of historical structures. The negative effect of lateral tension on the bond ...

Abstract: Fracture energy represents the average total energy consumption during a complete crack propagation process. The use of one fracture property, the RILEM fracture energy, on its own is not sufficient to characterize the ...

Abstract: This paper examines the fracture energy properties over ligament length for crack propagation process accompanied by fracture process zone (FPZ) advancement. Local fracture energy as well as its average value along the ...

Abstract: In RC structures during construction, the bond behavior of deformed bars in concrete is governed by the age-related concrete strength, the local confining pressure, the bar diameter, and the concrete cover thickness. In ...

Abstract: To ensure the safety of concrete structures under fatigue loading, the fatigue crack propagation in concrete needs to be evaluated accurately. In this paper, a numerical method for mixed mode I-II fatigue crack propagation ...

Abstract: A total of 32 fiber-reinforced polymer (FRP) confined concrete columns are manufactured and tested under axial compression including 8 FRP-confined solid columns (FCSCs), 4 FRP-confined concrete-filled steel tube columns ...

Abstract: Owing to its importance in evaluating the fracture behavior of concrete, the crack extension resistance curve of concrete has been widely studied, both experimentally and theoretically. In this paper, a numerical approach ...
