“…This view is supported by Cajka et al (2020) [45], who added that vertical and lateral loading is typical to be examined in the case of slab in building, especially in undermined areas. In flooring system, combined vertical and lateral loading has an important effect on the slab behaviour [46]. Slab behaviour under lateral loading also represents the global behaviour of a building experiencing sway and seismic movement has been studied recently by Alizadeh et al [47], Eladawy et al [48] and Isufi et al [49].…”

The fabrication of precast slab can be made from wide range of material either neat concrete, foamed concrete or even composite. Until recently, a new interest has been discovered. Instead of wet concrete mixing process in plant, the precast slab can be substituted with fibre cement board or commonly referred as cemboard that meets the specific load requirements with minimum thickness. However, cemboard panel is preferable for lightweight floor system due to its physical strength limitation. Its thickness that relatively small around 15 mm to 25 mm contribute to the drawback and subsequently prohibited the application of cemboard panel as heavyweight floor system. Small specimens are prepared to determine the optimum orientation of bolts and type of bond by analysing the bearing resistance and bond-slip behaviour. It was found that the bearing capacity is governed by polyurethane glue. Meanwhile, the bond-slip behaviour is effectively controlled by the steel bolt. If the steel bolt is solely used as bond mechanism, the bearing capacity will rely on its quantity and capacity and increasing the quantity of steel bolt will eventually lead to the higher value of bearing resistance.

“…In reality, however, superimposed loads in the two structures can vary significantly depending on their usage, floor/ceiling system, wall panels/partition walls, cladding, etc. In this regard, innovative structural solutions, such as prefabricated lightweight components using composite materials (cf., [66,67]), cellular/perforated beams with large web openings (cf., [68][69][70][71][72]), composite beams with precast hollow-core slabs (cf., [73]), and fully prefabricated lightweight flooring systems [74][75][76][77], can naturally find their application in MBS, with the potential of reducing imposed masses significantly. 3 rd storey IPE200 IPE220…”

“…The behaviour of two shear connection systems implemented in the proposed flooring system, namely, the horizontally oriented WWSS system and the horizontal dowels with WWSS system, were previously investigated experimentally under direct static shear force using the push-out test methodology and numerically by performing a finite element parametric study of PUSS slabs with three different concrete types; namely normal weight concrete (NWC), lightweight aggregate concrete containing Lytag aggregates (LWC), and ultralightweight aggregate concrete containing Leca aggregates (ULWC) [10]. As an outcome of that research, a formula for calculating the shear resistance of the shear connection systems was developed (Equation 1) [10]. = 1.873( ) 0.835 ≤ 0.8…”

This paper presents the results of a parametric finite element (FE) study that investigates the flexural behaviour and bending capacity of a recently developed steel‐concrete composite flooring system subjected to static bending tests. The flooring system is composed from prefabricated ultra‐shallow slab units (aka PUSS) that consist of T‐ribbed concrete floors encased within and connected to two C‐channel steel edge beams with horizontally oriented shear connections. The study considers three unique types of shear connection systems, that compose of only horizontally oriented web‐welded shear studs (WWSS), only horizontal steel dowels or a combination of horizontal steel dowels with WWSS. The failure mechanism, the shear resisting capacity of the shear connection systems and their behaviour under flexural loads are examined. The present work explores the influence of variable parameters on the performance of the PUSS flooring system. In particular, the parameters under critical investigation are the type, arrangement, and size of the shear connectors (WWSS and steel dowels) as well as the location of the main pressure caused by the applied load. Based on the results, the location of the applied loads contributed greatly to the behaviour of the shear connectors, moment resistance capacity and failure mechanism of the slabs. In addition, horizontal dowels provided greater bond between concrete and steel in comparison to WWSS.
