Dimensionamento de laje lisa maciça de concreto armado e laje Bubbledeck: estudo comparativo

Abstract

With the advancement and modernization of civil construction, there are several structural solutions that aim at the agility and practicality of construction, cost reduction, and sustainability, without compromising user safety and comfort. This work presents a description of the Bubbledeck slab system, an innovative solution that has been gaining ground in the national and international scenario. The Bubbledeck system consists of inserting plastic spherical modules into reinforced concrete slabs, evenly spaced between two steel meshes. With the purpose of analyzing the advantages and performance of this constructive system, a floor of an idealized structure was designed with the Bubbledeck slabs and with solid slabs. Then, a comparative analysis between these two systems was carried out, setting the same thickness for both, to evaluate the differences in terms of concrete volume, reinforcement rates, working forces, deflections and puncture resistance.
