| Summary: | This research aims to study the influence of steel fibers on the behavior of eighteen reinforced concrete (RC) slabs under different temperatures. The main investigated parameters in this paper were concrete type i.e. Normal-Strength Concrete (NSC), High-Strength Concrete (HSC) and Light-Weight Concrete (LWC), the effect of various parameters such as; amount of steel fiber ratio (0% and 2%) on failure load, crack patterns, and load- deflection response, have been studied. In these slabs the amounts of reinforcements were kept constant. The study also includes the type's failure and effect of types of concrete when all specimens are exposed to several temperature levels (25Co, 400Co, 600Co). It showed that, there is a reduction of strength with the increase of temperature. The test results show that as the volume of the steel fibers increase the punching shear strength increased and the presence of fibers delay the appearance of the first crack in the slab and gave less deflection than the slab without fibers.
