| Abstract | ||
| On the wise of structural advantages of flat plate slab systems, the researches still deal with punching shear hazards and solution techniques for adopting a rational design comes from experimental investigations. Beside that there is a rapid development in production the high performance concretes using chemical additives and wide spectrum of different features fibers which avail additional options for the structural designers. The present work is an experimental study adopts the comparison between uniform concrete sections with specific strength and hybrid sections (consists of two different layers with different strength in the top half and the bottom one) to provide reinforced concrete flat plate slabs and conclude the more advantage option for improving their behaviors against eventual punching shear failure. Normal strength, high strength and fibrous concrete with (34, 48 and 21) MPa compressive strength respectively are used to produce the slabs in this study. The results revealed the preference of the high strength uniform section in improving the slab behavior besides increasing its ultimate load twice in comparison with a hybrid section contains high strength concrete at the top half only and there is no advantage from increasing the tension zone strength on the hybrid section slab behavior except the ductility. | ||
