Abaqus Simulation of the Fire's Impact on Reinforced Concrete Bubble Deck Slabs

The use of Bubble Deck in modern prefabricated construction methods has recently become widespread industrial projects worldwide. In the middle a typical slab, places hollow plastic balls that do not improve structural performance but significantly reduce weight. This study analyzes behavior self-uniting bidirectional concrete slabs with spherical voids under high temperatures and for different periods. Six simply supported plates, five which contained bubbles one solid, were numerically tested using finite element method commercial ABAQUS software to investigate plates fired at various amounts time. Each slab following measurements: (1500*1500*150) mm. These (600 800) °C periods (one two hours). classified into four groups depending on kind (solid or bubble), degree burning °C, duration loading strength was found be up 65% less than maximum capacity bubbled temperatures. length firing time also had significant effect reducing concrete. longer period, lower load resistance ball would melt scorch an intense, protracted fire without noticeable effects. ability steel maintain adequate during fire, when it will burned lose as temperature rises, determines slab’s withstand fire. deck produce between 17% 39% stronger thermal equivalent solid same depth, even though they are intended provide insulation due encapsulation air within center slab.
