“…That is, to discover the elements that regulate hollow forms, such as shape, corner radius, and diameter, to better understand their impact on slabs, such as crack progressions and their concentration region. A three-dimensional model of a bi-axial hollow form in longitudinal and transversal directions was created using an optimized rectangular slab analysis [19,20].…”

The largest proportion of the material used in multistory buildings, and thus its carbon impact, is attributed to their slabs being the main contributor of weight. Because of their high strength and concrete self-weight reduction, composite beams with hollow-core slabs were created for their technical and economic benefits, making this system inexpensive and with a reduced environmental impact, thereby lowering carbon emissions. Geometrically, the hollow slab has a sequence of T and L form pieces on both sides. Hollow slabs are a newer roof feature with a little study undertaken in mechanical characteristics that prove its benefits and downsides in construction. It also has sufficient rigidity. In this work, numerous 19 hollow slabs and flat slabs are modeled using the finite element method, and the findings are compared in terms of hollow slab behavior and economic cost. It demonstrates that reducing the concrete beneath the hollow slab promotes cost-efficiency and the effective use of concrete and steel resources and various approaches for this form of the hollow slab are provided. Implementing a modern double-side beam slab is possible using the presented methods in this paper. It opens a door for creating structures with high stiffness and strength versus vertical and lateral load, along with low material volume.

“…However, heat is transferred directly into the concrete due to the deck plate rib and Y-shape flange, and the internal temperature of the slab rises compared to the general RC slab. As a result, the water vapor pressure is greater than the internal stress of the concrete, causing spalling [ 4 , 5 ]. Because spalling causes the concrete to fall out, it reduces the strength and usability of the member and causes the structure to collapse.…”

The purpose of this study was to evaluate the structural performance of composite deck slabs containing macro-synthetic fibers. after a fire by proposing a deflection estimation method for non-fireproof structural decks. Therefore, this study evaluated the fire resistance performance and deflection of deck slabs mixed with macro-synthetic fibers. Afterward, the deflection estimation method considering the thermal characteristics of concrete and deck plates was proposed. A material test was first conducted to evaluate the mechanical properties of concrete mixed with macro-synthetic fibers. This test found that the compressive strength and elasticity modulus of concrete mixed with macro-synthetic fibers was greater than that of general concrete. A flexural tensile test confirmed that residual strength was maintained after the maximum strength was achieved. The fire resistance of the deck slab was adequate even when a fire-resistant coating was not applied. The internal temperature was lowest for the specimen with macro-synthetic fibers. Deflection was evaluated using previously published equations and standards. The deflection evaluation confirmed that the temperature distribution should be applied differently in the estimation method that uses the thermal load of the deck slab.
