| description | Abstract: The deterioration of reinforced concrete structures due to exposure to fire and high temperatures remains a major challenge in structural engineering. High temperatures negatively affect the mechanical properties of concrete, particularly its load-bearing capacity, which can lead to premature structural failure before the designed service life. In this experimental study, five reinforced concrete slab specimens, each measuring 1000 × 400 mm, were prepared and tested. The concrete was poured with varying reinforcement ratios ranging from 0.0037, 0.009, 0.012, 0.0075, and 0.007, while the slab thicknesses ranged from 50 mm to 80 mm. The specimens were subjected to various thermal exposure conditions to evaluate the effects of fire-induced deterioration on their structural behavior. All specimens were then tested under a single-point central load at mid-span until structural failure occurred. The results indicated a significant decrease in the compressive strength and load-bearing capacity of concrete between (25-75%) at elevated temperatures |
