“…The ultimate shear load-bearing capacity at the steel-concrete interface in the shear specimens can be estimated using Equation (3), where the shear keys are analogized to shear studs [29]. In this equation, N v denotes the shear capacity of the steel-concrete composite specimen.…”

“…Pre-stressed concrete (PC) structures, widely utilized in contemporary architecture, are favored for their superior construction quality, lower labor costs, and faster project completion times [1]. Composite floor slabs, integral to PC residential flooring systems, combine a precast base plate with cast-in-place concrete, yielding robust structural integrity [2,3]. The design of these slabs necessitates reinforced connections to facilitate the coordinated load-bearing capacity of both post-cast and precast sections, with poorly executed designs potentially leading to structural vulnerabilities [4][5][6].…”

This study explored the tensile and shear characteristics of fully prefabricated partially composite floor slab joints through the design and testing of two tensile specimens, three steel–concrete specimens, and three concrete–concrete shear specimens. These tests aimed to evaluate how various connection designs influence the joints’ load-bearing capabilities and failure patterns. The findings revealed that the tensile specimens predominantly showed bond failures at the interface of the precast and cast-in-place layers, accompanied by rebar pull-out. Incorporating reinforcing bars or sleeves was found to potentially increase their ultimate load-bearing capacity by about 20%. The shear failures in the steel–concrete specimens were primarily due to interactions between the steel beam and adjacent composite slab, whereas the concrete–concrete specimens mostly underwent local crushing at the load application point and failure at the bonding interface. These observations affirmed the accuracy of the existing methods for calculating tensile and shear strengths, offering vital insights for the architectural design and construction of such floor joints.

<p>In order to apply a Modified-VFT (MVFT) steel-concrete composite girder to a continuous bridge, this paper investigates the structural configuration of the negative bending moment region of MVFT girder. Clothoid shaped composite dowels are designed in the hogging moment zone. Comparison studies were made for different geometric parameters of the connection. With the aim to increase the crack resistance of the concrete deck in the hogging moment region of the composite bridges, Ultra-High-Performance-Concrete (UHPC) is adopted. Wet joints schemes of shear studs and CL composite dowels are analysed.</p>
