Structural performance and failure analysis of bubbledeck concrete slabs in construction

Abstract

In this research paper, as the concrete material is eliminated from the locations situated around the middle of the cross-sections of bubbledecks (BDs), the BD type slabs are lighter than the traditional slabs. In the recent researches, the performance analysis (PA) is generally determined for the reinforced concrete (RC) structures with the moment-resisting frame (MRF) and dual systems. The dual system comprises mainly the MRF with shear wall of building under construction, as well as the flat slab having chiefly the BD system. In this paper, the evaluation of values of the performance and failure analysis of RC structures using BD system are submitted. We recorded a maximum load of 6.48, maximum stress of 75.00, macimum strain of 7.80, with minimum force of 0.83, while minimum slab length of 9.62 and lastly the maximum slab span of 27 for our bubbledeck concrete slab experiment in comparison with reinforced concrete slab to get the best results. The obtained results indicate that the lateral strengths of buildings increase by increasing the span length to story height ratio. Besides, the variations of the span length and the number of the story have more effects than the variation of the usage category buildings on the performance of structures. Furthermore, the span length has more effect than the number of stories in determining performance in an MRF. We observed that the bubbledeck concrete slabs are more lightweight and resistant in comparison with reinforced concrete.
