Abstract:
This article describes a new construction methodology for underpinning structures that use segmental precast concrete piles. Behavior of the proposed system at various limit states is presented based on an experimental program that was conducted to determine behavior under axial and eccentric loading conditions, as well as to determine flexural strength. The testing program used prototypes of the segmental piles to evaluate the ultimate load-carrying capacity and the mode of failure. A case study for using the proposed system for underpinning the 90-year-old Legislative Building of the Province of Saskatchewan is presented.
