Structural Behavior of BubbleDeck Slab under Uniformly Distributed Load

In structural construction fields, reducing the overall self-weight of structure is considered a primary objective and substantial challenge in civil engineering field, particularly earthquake-affected buildings tall buildings. Different techniques were implemented to attain this goal; one them setting voids specific position through structure, just like voided slab or BubbleDeck slab. The main research study behavior reinforced concrete slabs under effect static uniformly distributed load. experimental program involved testing five fixed-end supported two-way solid dimensions 2500×2500×200 mm. parameters included bubble's diameter 100 120 mm volume reduction 15 18 %. other parameters, which are compressive strength detail steel reinforcement, identical for all tested specimens be (? 10 @164 mm) reinforcement. outcomes indicated that ultimate load capacity decreased by 15.93 11.5 % compared case reductions %, respectively. On hand, an advanced behavior, including deflection, absorbed energy, ductility factor, was achieved; increments these 39, 5.3, 14.94 Doi: 10.28991/cej-2021-03091655 Full Text: PDF
