Abstract: Steel fibers in ultra-high performance concrete (UHPC) have been demonstrated to improve resistance to crack growth, decrease deflection, and increase fatigue life under cyclic loads. Using steel fibers as shear reinforcements, ...

Abstract: To optimally use the excellent mechanical properties of ultrahigh performance concrete (UHPC), this study experimentally investigated the flexural behavior of 10 lightweight steel-UHPC composite beams constructed using ...

Abstract: This paper reports the shear performances of steel wedge block–crossed inclined stud–ultrahigh performance concrete (UHPC) connections for application to steel-concrete composite bridges. The study entailed 36 pushout tests ...

Abstract: This paper reports on double shear push-out tests conducted on steel-to-ultra-high-performance concrete (UHPC) connections based on studs of 30- or 22-mm diameter in slabs of 35, 55, or 150 mm thickness. The results show ...
