As a competitive alternative for accelerated bridge construction (ABC), prefabricated steel–ultra-high-performance concrete (UHPC) composite beams containing high-strength friction-grip bolt (HSFGB) shear connectors offer numerous advantages, including reduced on-site time and ease of replacing/removing deteriorated components. However, the failure mechanism HSFGBs in UHPC remains unclear due to lack internal stress analysis, which hinders design these innovative beams. To clarify...
Precast concrete segmental bridges with dry joints have the advantages of rapid construction speed and low cost. The shear strength behavior castellated keys in precast are still debatable. In this paper, full-scale were tested under different confining stress levels. main parameters for tests number keys, stress, depth key geometry, distance between two keys. For comparison purposes, flat joints, monolithic steel fibers also tested. behavior, capacity, crack pattern investigated as well....
The deck slabs narrow joints in concrete bridges filled with Ultra-high performance (UHPC) have the potential for wide application and high-efficiency promotion, but there is limited research available on this topic. This paper conducted flexural tests new joints. Ten precast panels were designed manufactured bridges. These connected using UHPC-filled Combined stress analysis, study investigates influence mechanism of various factors mechanical UHPC include geometric shape joint, roughness...
Dry joints represent locations of discontinuity in precast concrete segmental bridges (PCSBs) through which compressive and shear stresses must be transmitted. Cracks dry occur more easily than those epoxy during the construction period or service. Steel fiber-reinforced (SFRC) with high rupture strength might beneficial to resistance joints. In this study, behavior various types PCSBs was investigated by experiments, especially focusing on keyed SFRC. The experimental parameters were joint...
Shear stirrups in a prestressed ultra-high performance concrete (UHPC) beam might be eliminated due to the high tensile strength of UHPC. This research aims investigate shear behavior externally UHPC beams without stirrups. Thirteen were tested with experimental parameters prestressing level, span-to-depth ratio, longitudinal reinforcement fiber content, and stirrup ratio. The results showed that ratio 2.0% under 2.0 failed flexure, even though additionally applying higher up 40% tendon....
This study numerically investigated the shear behavior of novel composite connectors, which consisted grouped head studs embedded in high-strength concrete-filled (HSC-filled) pockets. The pockets were prefabricated and retained open precast concrete slab. finite-element (FE) models established verified with full-scale test results. validated FE further used for parametric studies. In this study, strength stud connectors almost linearly increased diameter infilling strength. However, height...
Ultra-high-performance concrete (UHPC) is an advanced with superior mechanical strength, ductility and durability properties. However, the influence of steel fiber on its constitutive laws specimen geometric dimension effect strength had not been paid enough attention. To investigate fibers properties UHPC, specimens different volume contents types were tested. Meanwhile, UHPC at ages from 3 days to 28 conducted. Moreover, various dimensions also prepared study (dog-bone-shaped, prism...
To analyze the shear capacity and failure mechanism of perfobond strip (PBL) connectors in junction steel-UHPC composite pedestrian truss bridge, this study conducted monotonic loading push-out tests on four specimens PBL connector deeply embedded UHPC one specimen normal concrete. The research primarily investigated interfacial behavior under static load, focusing effects different concrete types, depth connector, diameter transverse reinforcing bar, especially situation with a deep 240 mm...
