Analysis of strength and flexure in bubbledeck slabs

Abstract

This study examines the structural behaviour of BubbleDeck slabs. This construction system was suggested by engineer Jorgen Breuning and is based on the principle that within the slabs, there is an area where concrete can be omitted due to its limited structural functions. By adding empty plastic spheres (also known as "bubbles") that have been previously spread out in this area, it is possible to significantly reduce the usage of concrete. The result is a reduction of approximately 35% in the slab's self-weight. The objective of this research is to experimentally evaluate the structural behaviour of BubbleDeck-type slabs under static and symmetrical loading. Specifically, the study aims to compare the performance of BubbleDeck slabs with current standards, verifying their deformation and maximum resistance. The study was conducted at the Structures Laboratory of the UniFacid University Center. Two solid BubbleDeck-type pieces were evaluated, simulating the panels subjected to bending and compression stresses. The methodology involved applying force to the panels to observe their deformation and the maximum resistance they could withstand. The results indicate that BubbleDeck-type slabs exhibit adequate structural behavior in accordance with current standards. The Study shows that this construction system is effective in reducing the self-weight of the slab and concrete consumption without compromising safety or compliance with structural standards. This makes the use of this construction system viable.
