Behavior of Precast, Prestressed Concrete Pile to Cast-in ...

tailed precast, prestressed piles can de velop and maintain large moments. Although a pile may be detailed to resist large forces, it is also necessary that the pile-to-pilecap connection be able to transfer these forces. There are only a few published investigations which report the behavior of the pile-to-pile cap connection. These studies

Precast, prestressed concrete sandwich wall panels are typically used for building envelopes. Such panels con-sist of two outer layers of precast, prestressed concrete separated by an inner layer of insulation. The panels can support gravity loads from floors or roofs, resist normal or transverse lateral wind loads, insulate a structure, and
