“…For the case study floor, since the span-to-thickness ratio was far greater than 20, thin-plate formulation was employed. Moreover, using thin plate elements for slab modeling is recommended in real applications since this method is more computationally effective than using solid elements and still ensures accuracy [28]. Neither drop panels nor interior beams were used in the case study floor.…”

Limiting vibrations to ensure occupant comfort is a serviceability requirement that should be considered in the design of floor systems. Current concrete design codes do not explicitly address the issue of vibrations when providing guidelines for calculation of the slab thickness of a flat plate floor. Concrete codes have introduced several methods of determination of the slab thickness or span-to-thickness ratio on the basis of deflection control. The objective of this article is to investigate to what extent a flat plate floor with codified minimum thickness would meet the requirement for walking-induced vibration control. The modal properties of flat plate floors spanning 6-9 m were determined and the 90th percentile velocity response to walking excitation was calculated using probability-based design charts developed by a European guideline on floor vibrations. For deflection control, on average the floor designed following the European concrete code was 6% thinner than the floor designed using the American concrete code and 34% thinner than the floor designed according to the Australian concrete code. It was interestingly found that the vibration of a floor that was dimensioned for deflection control as per any of the three concrete design codes well met the acceptance criteria for human comfort in office buildings, residential buildings, hotels and schools. In addition, the vibration of a 9-m-span floor whose slab thickness was determined using the Australian concrete code provisions could even be acceptable for critical areas.

“…May et al (2019) studied the required load-bearing capacity and deflection stiffness of precast slabs made of carbon reinforced concrete at conventional construction height and demonstrated that the slab concrete could be reduced continuously by optimizing the load-bearing structure. Rochman et al (2021) proved that lightweight foamed precast concrete slabs have good flexural behavior and can be used as a good prefabricated structural slab in the future. It can be seen from the literature review that the new slabs are mostly obtained by improving the form of composite slabs or changing materials, and the mechanical properties of slabs are explored through experiments and numerical simulation.…”

Prefabricated slab has been widely used in the global construction industry due to energy saving, environmental protection, and good economic advantages. In this paper, a new type of fully prefabricated staggered flip-down slab without cast-in-situ operation has been proposed. First, the experiments were carried out on the new slab. The structural performance of the new slab was compared with the cast-in-situ slabs and composite slabs of the same specification. The experimental results showed that the ultimate bearing capacity of the new slab meets the requirements for practical utilization. On this basis, an additional CFRP sheet could be pasted on the bottom initial seam between prefabricated slabs to enhance the integrity and prevent cracks. Then, the whole loading process of the slab was simulated, and the results were consistent with the experimental results. Finally, through experiments and parametric analysis, recommendations for improvement were put forward to enhance the mechanical properties of this kind of slab.

“…Concrete consists of cement, aggregate (coarse aggregate, fine aggregate), and water [13]. Advances in concrete technology enable lightweight structural aggregate concrete to be mass-produced with compressive strengths between 17.24 -41.36 Mpa [14]. The selection of the use of precast concrete is not only based on economic aspects, efficiency, and speed in its implementation [15].…”

This study aims to analyze the application of Precast Half Slab formwork with conventional formwork in terms of cost, time, and implementation stages. The method used in this study is the precast half slab method. The Batang I Industrial Worker Flats project is in the Batang Integrated Industrial Estate. In the highly advanced construction era, many projects compete to innovate to produce a fast and efficient building. This Project uses the precast half slab method, where half of the floor slab is printed offsite (precast) with a thickness of 7 cm, and the other half is in place (topping 5.5 cm). This final Project analyzes the precast half slab method used by comparing it to the conventional method in terms of cost and time, so it can be seen which method is more profitable. The precast half-slab method analysis focuses on calculating the direct cost of conventional half-slab precast in terms of materials, tools, and worker wages, as well as calculating the time needed for each job.
