The helical pile as foundation has been widely used for light application load. It consists of helically or multiple shaped plate attached to a central shaft with diameter ranging from small to large in both shaft and helix. When helical pile is installed on proper soil layer, it can esist the load for both compressive and tension load. The sum of capacities gained from each individual helical plate then defined as the total capacity of helical pile. This paper is aim to study the uplift capacity of helical pile on the helical size effect. Uplift loading test were performed on two different types of helical piles, uniformly sized plate and tapered sized plate installed on clay soil soil. Diameter of plate used are 15 cm, 20 cm, and 25 cm spaced far enough apart about S/D < 3 of the largest helix diameters. The results of this study indicate that the rate of capacity is variable, considering the helical size configuration. Various helix diameter attached on the shaft in the helical pile increased the uplift capacity up to 50%. The effect of helical size to uplift capacity is briefly demonstrated on this study
