RISFlexural Performance of Steel–UHPC Composite Beams with Innovative Steel Wedge Block–Crossed Inclined Stud Connections
Publisher: American Society of Civil Engineers
Abstract: This paper presents an experimental study on steel–ultrahigh performance concrete (UHPC) composite beams using the steel wedge block–crossed inclined stud (SWBCIS) connections. The effects of stud inclination angles, shear ...
Effect of Steel-Fiber Shear Reinforcement on Postcracking Shear Fatigue Behavior of Nonstirrup UHPC Beams
Publisher: ASCE
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, ...
Flexural Performance of Ultrathin UHPC Slab–Steel Composite Beams with Ultrashort Stud Connections
Publisher: ASCE
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 ...
Development and Performance of Innovative Steel Wedge Block–Crossed Inclined Stud–UHPC Connections for Composite Bridge
Publisher: ASCE
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 ...
Parametric Experimental Study of Ultra-Short Stud Connections for Lightweight Steel–UHPC Composite Bridges
Publisher: ASCE
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 ...
