الملخص

In this research the punching shear behavior of Self-Compacted bubble RC slab was investigated after burning it in real fire test until reach 300 C° and cooling it by air and water Experiment results show that using self-compacted concrete improves the cracking pattern and punching failure zone due to improvements in the microstructure of the concrete and how it fills voids and makes contact with the plastic ball. The ultimate load increased by (13) % when using SCC with the same fć, and the effect of water cooling was reduced compared to its effect on normal concrete due to SCC's lower permeability, but the effect of spalling made self-compacted concrete more sensitive to high temperatures.
