Rigid pavements have been used broadly in airfield constructions. As the pavement design is expected to deliver acceptable performance along its service time under wide-ranging circumstances. The concept of the load transfer is crucial in pavement design procedures. Many researchers investigated rigid pavement in airfields based on the finite element method. Despite the notable enhancement, significant concerns were overlooked. These simplifications to the developed models may affect the results of the developed models and make them unrealistic.

Nowadays, several research are concerned with studying the effect of voids in concrete elements specially voided slabs. The concept of voided concrete slabs depends on removing inactive concrete parts without affecting performance of the elements. This can be accomplished by replacing inactive concrete by hollow plastic forms. There are many systems that adopt this concept like cobiax, bubble deck, U-boot, Bee plate, and donut. This research reviews many experimental and numerical studies concerning voided slabs to shed light on their design methods, their advantages and disadvantages, their comparison with other common flooring systems, and finally the possibility of their application in Egypt.

The main objective of the following work is to inspect the effect of reinforcing metal mesh on the behavior of slabs with openings under impact loadings. Based on an earlier numerical study by Shaheen et al. (2017), slabs with mid-side openings revealed the worst behavior regarding to deflection and cracked pattern when subjected to impact loading compared to other slabs with different locations of openings. Hence, the present work focuses specifically on this type of slabs and the variation in their behavior when reinforced by welded or expanded metal mesh. Seven specimens were prepared and tested in Faculty of Engineering, Menoufia University, Egypt. Moreover, a FE model for the slabs was built using Abaqus 6.14 and verified against test results. It was found that expanded metal mesh had a significant effect on reducing deflection due to impact load as well as controlling of cracks in contrast with welded metal mesh.
