Punching shear behavior of LWA bubble deck slab with different types of shear reinforcement

Bubble Deck Slab System: A Review on the Design and Performance

“…Despite the fact that the spherical form is the common shape for the void formers, however, according to Jamal & Jolly, (2017) and Mohan & Sukumaran, (2018), the studies have shown that bubble deck slab with elliptical balls has a better load carrying capacity and lighter in weight compared to the spherical balls. Nonetheless, the statement of elliptical void formers having better load carrying capacity is contradicted with the study done by Habeeb et al, (2021), the finding shows that the bubble deck slab with spherical balls has better load-bearing capacity than those with elliptical balls with the same ratio of bubble diameter to slab thickness.…”

Experimental and Theoretical Design of Reinforced Bubble Deck Concrete (RBDC) Slab: A Review

“…Additionally, while the spherical shape is commonly used for void formers in bubble deck slabs, recent studies by Jasna et al, [14] have indicated that elliptical balls offer superior load-carrying capacity and reduced weight compared to spherical balls. However, it is essential to note that this claim contradicts the findings of a study by Maha et al, [15]. As reported by Maha et al, [15], bubble deck slabs with spherical balls exhibit superior load-bearing capacity compared to those employing elliptical balls, with an approximate advantage of 3.7% and 9.7%, respectively, when maintaining an equal ratio of bubble diameter to slab thickness.…”

“…Jasna et al, [14] Finite Element Analysis: ANSYS software The load-bearing capacity of a Reinforced Bubble Deck Concrete (RBDC) slab equipped with elliptical balls surpasses that of a Bubble Deck slab incorporating spherical balls. Maha et al, [15] Experimental: Static Load Testing with a maximum load of 1000 kN Comparing Reinforced Bubble Deck Concrete (RBDC) slabs with spherical and elliptical balls under identical bubble diameter to slab thickness ratios, the former exhibits a superior load-bearing capacity by approximately 3.7% and 9.7%, respectively.

“…Also, (Singh et al, 2022), (Singh et al, 2021), (Singh et al, 2021) in their studies have presented the parameters, empirical equation along with experimental validation for the shear as well as the flexural design of High strength concrete. (Habeeb et al, 2019), (Habeeb et al, 2021), studied the punching shear in flat slabs made with Lightweight aggregate concrete having compressive strength up to 43 MPa. (Ojha et al, 2021), (Ojha et al, 2020) performed a series of experiments to evaluate the creep and shrinkage properties of high-rise buildings.…”
