Abstract The flexural behavioral properties of ultra high performance concrete (UHPC) low-profile T-beams reinforced with a combination steel fibers and reinforcing bars were investigated in this paper. Five large scale tested analyzed regarding their deflection, ductility, strain, curvature, load capacity crack development. experimental variables include the reinforcement ratio, slenderness (length to diameter ratio) fiber reinforcements, type. experiments showed that all specimens exhibit...
In traditional mold-casting for concrete, the process of assembling and demolding formwork is both costly time-intensive, limiting design possibilities complicated shaped composite applications. Autonomous or semi-autonomous 3D concrete printing presents an innovative solution, allowing customization intricate shapes facilitating creation structures. This study develops manufactures a novel beam that incorporates 3D-printed (3DP) ultra-high performance strain-hardening cementitious...
Abstract The flexural cracking behavior of ultrahigh performance concrete (UHPC) beams was experimentally studied in this paper. Eight UHPC were tested and analyzed regarding their crack pattern, spacing load‐crack width curves. test variables included reinforcement ratio, diameter cover thickness. results indicated that increased linearly with the increase applied load until yielding steel rebars. When beyond load, one or two cracks developed into localized cracks, followed by a rapid...
Abstract This paper experimentally investigated the flexural and ductile behaviors of ultra‐high‐performance concrete (UHPC) beams. The failure modes, deflection, ductility, strain, reinforcement strain were tested using eight UHPC rectangular experimental parameters ratio, diameter, cover thickness. results showed that all specimens exhibited characterized by yielding steel rebars, multiple micro‐cracks, one localized macro‐crack, slight crushing UHPC. It was concluded increasing ratio...
Ultra-high-performance fiber reinforced concrete (UHPFRC) exhibits strain hardening and multiple cracking behaviors when subjected to tension load. There are limited studies on the effect of steel aspect ratios tensile performance UHPFRC. Also, testing cementitious materials composites is challenging due lack a standardized direct method with wide variation. This study experimentally investigated hooked end straight behavior UHPFRC 2% volume fraction. A test setup was first developed obtain...

Abstract To enhance the mechanical and constructional performance of ultra‐high concrete (UHPC) beams, steel plate placed at bottom surface UHPC beam is utilized to replace ordinary rebars. In this paper, four 3.2 m T‐shaped beams with different reinforcement patterns rebars external were fabricated comparatively tested under flexure loading. Their damage patterns, load versus deflection behavior, flexural capacity, strain moment curvature stiffness, crack development investigated. The...

To enhance the structural performance and durability of a conventional reinforced concrete (RC) cover slab over culvert as well to improve its spanning ability, this paper presents novel ultrahigh-performance (UHPC)-RC composite with clear span 8 m. The inverted prefabricated UHPC single-Tee or double-Tee beam was placed at bottom cast-in-place normal strength form UHPC-RC slab. A full-scale experimental test on conducted explore quantify mechanical performance. characteristics slab, such...
Abstract Connections in the assembled precast elements become essential locations for creating structural continuity. However, construction challenges of conventional steel sleeve connections, such as rebar embedment length, congestion, and formed grout defects (i.e., voids), are still a concern area researchers engineers. In this study, proposed ultrahigh performance concrete (UHPC) grouted connection was presented elements, which might reduce defects, enhance durability, accelerate...
