  • Experimental and Numerical Analysis of Bubbles Distribution Influence in BubbleDeck Slab under Harmonic Load Effect
  • Abstract-Reducing a structure’s self-weight is the main goal and
    a major challenge for most civil constructions, especially in tall
    buildings and earthquake-affected buildings. One of the most
    adopted techniques to reduce the self-weight of concrete
    structures is applying voids in certain positions through the
    structure, just like a voided slab or BubbleDeck slab. This
    research aims to study, experimentally and theoretically, the
    structural behavior of BubbleDeck reinforced concrete slabs
    under the effect of harmonic load. Tow-way BubbleDeck slab of
    2500mm×2500m×200mm dimensions and uniformly distributed
    bubbles of 120mm diameter and 160mm spacing c/c was tested
    experimentally under the effect of harmonic load. Numerical
    analysis was also performed with the ABAQUS software. The
    results of the adopted numerical model were in acceptable
    agreement with the experimental results. The numerical analysis
    presented by the bubbles distribution effect was carried out for
    the BubbleDeck two-way slab under the effect of harmonic load
    through the evaluated numerical model. Two cases were
    considered in which the distribution kept the critical positions of
    the slab free from the bubbles. The results proved that bubbles
    distribution significantly affected the structural behavior.
