“…Meanwhile, Lee et al [ 9 ] evaluated the new deck plate system. Moreover, Kang and Kim [ 10 ] studied new end details for replacing vertical bars with a shear connector as a new technology. These studies reported that the deflection values of deck plates with various end details were similar, and the studies were satisfied with the limitation of deflection in codes [ 8 , 9 , 10 , 11 ].…”

Deflection Test of Wire-Integrated Steel Deck Plates with Various End Details

et al. 2023

This experimental study was conducted to evaluate the deflection performance of wire-integrated steel deck plates with various end details subjected to cumulative gravity loads. In general, when deck plates are installed in the Republic of Korea, vertical bars are mounted at the ends of the wire-integrated deck plates. However, this process can extend the construction time, thus incurring additional costs. Consequently, this study aimed to examine the structural performance of a deck plate when a lattice foot—rather than a vertical bar—is installed at the end of it. A total of nine specimens were prepared; the experimental variables included the end details, height of the lattice truss girder, and structure type. To evaluate the deflection performance, the cumulative gravity load (as a construction load) and a concrete self-weight were applied to the specimens, and the deflections of each specimen were measured. In the experimental results, the deflection values of the specimen with vertical bars were 0.9~6.1 mm, while those for the specimen without vertical bars were 0.8~5.0 mm. This means that a lattice foot exhibits better deflection performance than conventional end details. Additionally, the deflection of the specimens satisfied the deflection limits required in the relevant standards.

“…A wide variety of deck-plate structural and manufacturing systems have been developed by many research institutions and construction companies due to their better structural performance and inherent construction efficiencies [1][2][3][4]. The deck plate serves as a form for concrete placement, thereby reducing the construction period and expense, noting that the concrete formwork generally occupies approximately thirty percent of the total construction cost [5]. Also, the deck-plate systems provide work space and the deck plate itself plays a role as a flexural member, which can resist the self-weight of concrete to pour and the workload during the construction period.…”

“…The deck-plate system integrated with truss girder by welding has been frequently used these days because of its structural performance suited to high-rise and long-span buildings [3,6]. The structural safety of this truss deck plate has been evaluated and verified by several researchers [5,[7][8][9][10][11], and they are currently being used in a number of construction sites.…”

This paper presents an experimental and numerical study to investigate the structural performance of a steel deck-plate system bolted with truss girder. This system has been proposed herein to resolve the issues caused by welding. Structural tests for six full-scale specimens were performed to ensure the structural safety of the proposed system based on design criteria for deflection. Local responses with an emphasis on the failure modes of the system were also assessed using the measured strains at the locations where stresses are localized. Numerical models for all test specimens were developed with the material test data and were validated based on the test results. The structural behaviors of the proposed system, not confirmed in the tests, were further examined using numerical simulations, with a focus on the failure mechanism between the numerical predictions and the test results. Appl. Sci. 2019, 9, 3166 2 of 18 slab) to solve these sorts of problems. This system involved pressure joining in lieu of spot welding to connect lattice to galvanized steel sheets and does not require welding, thereby not suffering an oxidation-induced rust. For this non-welding deck-plate system, there is, however, still a limitation that the deck plate is hard to decouple from the slab, which makes checking the crack, if any, inside the slab and recycling the deck plate difficult.This study thus proposes a deck plate, made of galvanized steel sheet, connected by bolts rather than welding to enable the deck plate to be reused, thereby preventing corrosion for the deck plate, facilitating grasping of the cracks of the slab, and developing an eco-friendly construction method for deck plate. Six full-scale tests were performed to investigate the structural performance of the proposed deck-plate system bolted with truss girder. Three slab depths of 135, 150, and 200 mm and the corresponding span lengths of 3200, 3800, and 4500 mm, respectively, were considered. Local failure modes were examined using measurements from plastic strain-gauges. A numerical study was then performed using a finite element code, LS-DYNA [14,15], to ensure that the observations from the tests were reliable and to further investigate the global and local responses, which were not confirmed during the tests. The numerically derived failure modes are discussed in detail by comparison to the test results. Deck Plate Bolted with Truss GirderThe deck-plate systems bolted with triangular truss girder, as introduced previously, are produced automatically by the machine at the factory, such that this slab system is manufactured under well-organized quality control and can maintain a constant spacing of reinforcing bars with yielding high-quality products. Since the truss girder and the galvanized steel sheet are assembled by bolts, the steel sheet can be disassembled after the completion of the construction, by simply dismantling the bolts after the concrete pouring and curing are finished. Accordingly, this deck-plate system can be considered as an eco-friendly ...

In this study, we propose a new truss deckplate system, which does not require temporary floor supports during construction, with ultra-high-performance concrete (UHPC) infilled top bars. The increased stiffness and strength of the proposed system were well retained as compared to those of the existing truss deckplate systems, thereby resulting in the reduction of maximum deflection at the span center. Four-point bending tests were performed on five specimens with a net span of 4.6 m to evaluate the structural performance of proposed system in the construction stage. In addition, the load-deflection curve was plotted for each specimen, and the effects of test parameters were analyzed. Further, a rigorous nonlinear three-dimensional finite element analysis was performed, and its results were compared with the test results. From the results, it was observed that the test specimens of the proposed system exhibited superior performance as compared to those of the existing one and also satisfied the serviceability requirement during construction provided by the Korea Building Code 2016.
