Size Effect on Static Splitting Tensile Strength of Concrete: Experimental and Numerical Studies
Publisher: ASCE
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 ...
Numerical Modeling of Flow Through Phloem Considering Active Loading
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Effect of Initial Static Load and Dynamic Load on Concrete Dynamic Compressive Failure
Publisher: ASCE
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 ...
Size Effect on Compressive Strength of GFRP-Confined Concrete Columns: Numerical Simulation
Publisher: ASCE
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 ...
Novel Size-Effect Law for Shear Strength of CFRP-Strengthened Lightweight Concrete Deep Beams without Stirrups
Publisher: ASCE
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 ...
Effect of Size on Eccentric Compression Behavior of CFRP-Confined RC Columns: Experimental and Numerical Investigation
Publisher: ASCE
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 ...
Effect of Initial Static Loadings on Dynamic Shear Performance of BFRP-Reinforced Concrete Deep Beams
Publisher: ASCE
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 ...
Experimental Investigation of the Bond Performance between Nonuniformly Corroded Reinforcing Bar and Concrete
Publisher: ASCE
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 ...
Static–Dynamic Universal Strength Criterion for Concrete Material
Publisher: American Society of Civil Engineers
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 ...
Investigation on the Impact Response of Concrete Beams Reinforced with Hybrid Steel–BFRP Bars
Publisher: ASCE
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 ...
