Abstract

Nailed-slab Pavement System is a new kind of rigid pavement which proposed by Hardiyatmo (2008). This system consists of a thin reinforced concrete slab, and short piles attached underneath. The installed piles under the slab were functioned as slab stiffeners and anchors. Its performance due to compression loadings were conducted by some researchers. Puri, et.al (2015) reported pull out test on 1-pile row Nailed-slab System. In this paper, the finite element analysis will be done by using the test results from Puri, et.al (2015). According to Puri, et.al (2015), the full scale of 1 pile row Nailed-slab System was conducted on soft clay which consisted of 6.00 m x 1.20 m slab area with 0.15 m in slab thickness, 5 short micro piles (0.20 m in diameter, 1.50 m in length, and 1.20 m in pile spacing) as slab stiffeners which installed under slab. Piles and slab were connected monolithically, then in due with vertical concrete wall barrier on the two ends of slab. The system was loaded by pull out loading on the end of slab. The tested model has sufficiency uplift resistance and linear elastic behavior can be reached the load 13.3 kN (Puri, et.al, 2015). Behavior of Nailed-slab Pavement System can be good modeled in linear elastic zone. Contribution of vertical barrier due to pull out loading should be taken in further research. Anchorage resistance of piles was contributed to the uplift resistance. This uplift capacity is very important to resist the uplift loads around the end of slab
