Evaluation of the Floor Impact Sound Insulation Performance of a Voided Slab System Applied to a High-Rise Commercial Residential-Complex Building

Shear Reinforcement Effectiveness of One-Way Void Slab with the Hollow Core Ratio and Shear Reinforcement

“…Solid slab systems, an early innovation aimed at expediting construction and reducing costs by eliminating intermediate beams, remain one of the earliest methods introduced for such purposes [1,11,14]. Nevertheless, the substantial weight associated with this system renders it unsuitable for application in long spans and high-rise structures [10,[15][16][17][18]. Additionally, its increased weight contributes to heightened seismic loads, rendering its utilization in regions prone to high seismic activity economically unfeasible [4,19,20].…”

“…Several reports suggest that the adoption of void slabs, which involve a reduced amount of concrete and incorporation of recycled materials for void formers, can align with the objectives outlined in building environmental assessment methodologies such as BREEAM and LEED [21,22,27,28]. Moreover, void slab structures are expected as potential solutions to societal issues like inter-floor noise in densely populated high-rise residential settings such as apartments and high-rise buildings [17,[29][30][31].…”

Floor impact noise performance of prefabricated prestressed joists and block slabs with wooden laminate floors

“…The floor impact noise level is influenced by the physical characteristics of the floor covering, in addition to the boundary conditions (volume of the room, finishing materials of walls and ceiling) (NA et al, 2019;YU;KANG, 2009). Floor systems are elements of horizontal compartmentalization that separate housing units in buildings, whose sound transmission of impact noise occurs on a daily basis, due to falling objects, dragging furniture and footsteps.…”
