Static and cyclic behaviour of Bubble Deck slab with plastic balls

Abstract
Bubble deck slab technology offers an innovative approach for crafting concrete slabs that combine lightweight properties with efficiency. This system incorporates voids within the system. The primary purpose of voids is to minimise the self-weight of a slab considering its structural integrity. This enables extended spans and decreases the load on the supporting structures. This study investigated the static and progressive cyclic load behaviours of concrete in which plastic balls were used as void makers below the neutral axis in various proportions. Bubble deck slabs were evaluated alongside conventional concrete under both loading conditions, and the results were analysed to assess the impact of varying void percentages. In addition to the primary investigations, a detailed analysis of the load–deflection curve behaviour and stiffness degradation of the slabs was conducted.
