“…and an increase in yield deflection (Δy) and ultimate deflections (Δu) of steel fiber bubbled slabs (0.5%S.F.B.S , 1%S.F.B.S ,1.5%S.F.B.S) by (11.7% ,17.2% ,28.1) respectively for yield deflection and (10.5%, 21.4%, 37.3%) for ultimate load compared to solid slab (S.S). And increase yield deflection (Δy) and ultimate deflections (Δu) by 17.4%, 28.8%, 46%) for yield deflection respectively and (53% ,68%,90.2%) respectively for ultimate deflection compared with bubble slab (B.S) as shown in Figure (2). This increase is attributed to the presence of steel fiber in the bubble slab, which gives concrete ductility characteristics.…”

“…Due to their substantial dead weight and increasing inertia forces, heavy structures are less resistant to seismic shocks than light ones. Finish material costs rise when support beams are added at a floor-to-floor height [1,2]. The "Bubble-Deck System," developed in the nineties by (Jorgen Breuing), was designed to eliminate the slab's weight.…”

Utilizing Bubbles in the slab is a revolutionary way to get rid of the concrete in the middle of a traditional slab; since this concrete serves no structural purpose and adds a lot of dead weight to the structure, using a bubble in the slab will weaken the slab and reduce its efficiency by (10%), this research presents an experimental study of steel fiber effects on bubble slabs and checks if steel fiber covers the messing efficiency and the effect on the type of failure. The program for the experiment is to test five slabs with (1760 mm × 420 mm × 125 mm) dimensions, divided into one solid slab without bubbles and steel fiber, one bubble slab without fiber, and three bubble slabs with three different fiber percentages, the experimental results shows that the three steel fiber bubble slabs (0.5%S.F.B.S, 1%S.F.B.S, 1.5%S.F.B.S) show an increase in yield load and ultimate load by (16%,20%,26.3%) for yield load and (14.5%,20.26%,25.2%) for the ultimate load respectively compared with the solid slab (S.S), and increases yield load and ultimate load by (31.8%,36.36%,40.9%) for yield load and (26.8%,33.2%, 39.8%) for ultimate load compared with bubble slab (B.S), for first crack load in solid slab (S.S) and bubble slab (B.S) first crack appeared at (13kN, 11kN) and for steel fiber bubble slabs (0.5%S.F.B.S, 1%S.F.B.S, 1.5%S.F.B.S) first crack appeared at (18 kN, 22 kN, 24 kN) respectively and change of type of failure from brittle sudden shear failure for the bubble slabs to ductile flexural failure.

“…Furthermore, the installation of plastic hollows decreases the moment of inertia of the cross section, which in result reduces flexural stiffness of the structure. For this reason, concrete slabs with hollows usually demonstrate a larger deflection than solid slabs of same external dimensions [ 10 , 11 , 29 , 30 , 31 ].…”

The article deals with experimental and numerical research of the layered reinforced concrete slab with plastic inserts. The investigated layered reinforced concrete slab is made of prefabricated and monolithic reinforced concrete layers. Voids were formed in the plate with spherical plastic inserts. With reference to the built-up bars theory, the paper proposes an analytical method for calculating the deflection of the layered reinforced concrete structures in non-linear stage, when bond between layers is partially rigid. The article also focuses on the numerical simulation of the layered slab, compares the estimated theoretical values of deflection with the experimental values and assesses the shear stiffness of the bond of prefabricated and monolithic concrete layers for calculating the deflection of the reinforced concrete slab. Paper presents the parametric analysis of deflection dependence on shear stiffness and the width of the contact zone of the layers. It was established that proposed analytical method and numerical analysis properly characterise the behaviour of the slab. Calculation results were close to experimental data. Moreover, it was determined that performance of this type of slab is highly influenced by shear stiffness of the bond between the concrete layers. Analysis confirmed that slab fails when bond is damaged, and layers slip in the support zone.
