 note = {application/pdf, In this paper, the effects of top and bottom layers on shock absorbing performances of a 3-layered cushion system using RC core slab reinforced with Aramid Fiber Reinforced Pastic (AFRP) rods are discussed on the basis of experimental results. This system consists of RC core slab, sand and/or Expanded Poly-Styrol (EPS). In order to study the effects of top and bottom layers on the shock absorbing performances, both material and thickness of top and bottom layer were changed. Furthermore, these results were compared with the results when single sand layer was used as cushion material. The experiments were conducted by a free drop of 3 tf heavy weight from a height of 30 m on the center of the cushion system. The results achieved from these experiments are: (1) Transmitted impact force can be effectively decreased by using thicker sand layer in top and EPS in bottom. (2) Impact force in case using sand in bottom layer are bigger than in case of single sand layer. (3) Thickness and material of top layer are more effective against the crack pattern of RC core slab.},
