10.2 Concrete Piles Conrete piles may be precast,prestressed,cast in place,or of composite construction. Precast concrete piles-piles are formed in a central casting yard to the specified length,cured,and then shipped to the construction site. -precast piles may be made using ordinary reinforcement or they may be prestressed. ■ -using ordinary reinforcement are designed to resist bending stresses during pickup and transport to the site and bending moments from lateral loads and to provide sufficient resistance to vertical loads and any tension forces developed during driving. -the minimum pile reinforcement should be 1 percent. -bending moments developed during pickup depending on the location of the pickup point.10.2 Concrete Piles ◼ Conrete piles may be precast, prestressed, cast in place, or of composite construction. ◼ Precast concrete piles-piles are formed in a central casting yard to the specified length, cured, and then shipped to the construction site. ◼ -precast piles may be made using ordinary reinforcement or they may be prestressed. ◼ -using ordinary reinforcement are designed to resist bending stresses during pickup and transport to the site and bending moments from lateral loads and to provide sufficient resistance to vertical loads and any tension forces developed during driving. ◼ -the minimum pile reinforcement should be 1 percent. ◼ -bending moments developed during pickup depending on the location of the pickup point
