Finite Element Modelling and Analysis of Hollow and Concrete Infilled Spun Pile

Abstract

In the medium to high seismic zone, spun pile for structural foundation should be designed with elastic behaviour due to low ductility and dissipated energy. Spun pile is also termed as prestressed hollow concrete pile (PHC). Spun pile is one of the types of piles are widely used in the world construction, for example in building and bridge. However, it is important to note that spun piles have limited ductility so that they are not intended to response inelastically during major earthquakes. spun piles behave brittle manner in both axial force domination and flexural moment domination. Recently spun piles are commonly used directly as the piers of elevated slab such as viaduct called pile-supported slab viaduct (PSSV). In this paper the hollow spun pile is infilled with concrete and concentric load analysis is carried out. Then comparing the axial load carrying capacity of hollow and concrete infilled spun pile.
