“…In this study, reinforced foam concrete flat slabs were exposed to fire under eccentric and concentric loads. e validity of the adopted models was verified through comparison with a previous experimental study which has been conducted by Riad and Shoeib [18]. By using the software analysis (ANSYS), crack patterns, load-deflection curves, steel strains, and deflection during the fire were analyzed in this study.…”

Lightweight reinforced concrete (LWC) is widely used in various reinforced concrete (RC) applications, such as its use in diverse types of reinforced concrete slabs. The aim of this study is to analyze the behavior of reinforced foam concrete slabs (flat slab type) that are exposed to fire conditions under the influence of eccentric loads as well as concentric loads. This analysis has been done using the finite element method by a (ANSYS) software program. The validity of the adopted models was verified through comparison with a previous experimental study. The studied specimens were eleven reinforced concrete flat slabs with a thickness of 150 mm. The lightweight polystyrene foam concrete was used in these specimens with a density of 1820 kg/m3. The results showed that the fire effect lead to a decrease in the maximum carrying load of foam concrete slabs by 25%. Also, by comparing the finite element results with the selected experimental study, the results showed a great agreement with the analytical study used in this research.

Voided concrete slabs have emerged as a good alternative to solid slabs in many applications due to their excellent advantages. Although these slabs have a good thermal insulation ability, they have a disadvantage represented by their low fire resistance, this defect may affect the structural performance of bubbled slabs subjected to elevated temperatures more than that of the solid slabs. Since there is a considerable lack of knowledge about this effect, this paper presents an empirical exploration on the impact of exposure to elevated temperature on the structural performance of voided reinforced concrete two-way slabs. The empirical plan includes construing and testing eight voided reinforced SCC slabs subdivided into two groups to study the effect of the exposure to different elevated temperature degrees and the exposure period to the elevated temperature. The outcomes reveal that increasing the temperature from 100 to 400℃ makes the first crack of the voided slabs decreases from 9.4% to 35.2%, the ultimate load decreases by 10.7% to 38.2%, and the ductility ratio decreases from 7.1% to 28.6% respectively, while increasing the exposure period from 1hr to 4hrs. leads to decreasing the cracking load from 35.2% to 62.8%, the ultimate load from 38.2% to 63.2%, and the ductility ratio decreases from 28.6% to 38.1% respectively. Also, the results show that it is necessary to avoid using this type of slab in buildings exposed to high temperatures exceeding 100℃, significantly when the exposure period exceeds one hour.
