Abstract
Theapplications of chiken foot foundation (sistem cakar ayam) are shown successfully on run
way, taxi way, and apron of airport and gave services more than 30 years. This system is also
shown the satisfy performance for high way construction. One of developing of this system
was changing the concrete cylindrical foundation by galvanized cylindrical steel and it is
named modified chiken foot foundation (CAM). Hardiyatmo (2008) proposed Nailed-slab
System for more practical application by changing the cylindrical foundation by concrete pile
foundation. Based on model tests and analysis, the Nailed-slab is promising for application.
This research is aimed to learn the behavior of Nailed-slab by conducting parametric study.
This study was using the full scale test results of chiken foot foundation in Waru, East Java.
Results show that the performance of Nailed-slab system (4 × 4 piles and 5 × 5 piles)with
similar slab width with CAM was better than CAM performance. Slab deflections of Nailedslab
tend to be lower than CAM. Similar behaviorswere for moment of slab. Additional of pile
length and decreasing the pile spacing can increase the performance which indicated by
decreasing the deflections.
