Abstract: Although there are numerous experimental studies of the size effect on nominal splitting tensile strength of concrete materials being performed, research on effect of specific material parameters involving maximum aggregate ...

Abstract: Transport through phloem is of significant interest in engineering applications, including selfpowered microfluidic pumps. In this paper we present a phloem model, combining protein level mechanics with cellular level fluid ...

Abstract: Concrete structures often suffer from multiple dynamic loads, or prior to being subjected to dynamic loads have already withstood initial loads. The mechanical properties of concrete materials under dynamic loads may be ...

Abstract: The available researches on concrete columns confined with fiber-reinforced polymer (FRP) laminates have not comprehensively addressed the size effect. In this study, a three-dimensional mesoscale simulation approach that ...

Abstract: Several size-effect laws (SELs) have been proposed and verified for concrete-like quasi-brittle materials. However, there is no SEL that can quantitatively describe the influence of related factors on size effect in carbon ...

Abstract: Few studies have investigated the eccentric compression behavior of fiber-reinforced polymer (FRP) confined reinforced concrete (RC) columns. In particular, the studies on the eccentrically loaded large-sized FRP-confined ...

Abstract: To better understand the effect of initial static loading on the dynamic shear performance of concrete deep beams reinforced with basalt fiber–reinforced polymer (BFRP) bars, a three-dimensional mesoscale numerical model ...

Abstract: In this study, bond failure tests were carried out on eight beam anchorage specimens after accelerated corrosion, and the crack widths on the concrete surface and the nonuniform corrosion characteristics of the reinforcing ...

Abstract: Studies on the biaxial strength criterion provide a significant theoretical basis for the exploration of concrete material’s biaxial and multiaxial mechanical properties. In this study, mesoscopic modeling of concrete cube ...

Abstract: An appropriate hybrid form of steel and fiber-reinforced polymer (FRP) bars in reinforced concrete members can prevent steel corrosion and ensure capacity and ductility. To investigate the impact resistance of concrete ...
