This investigation studied the capacity of square pile-to-pile cap connections where the precast-prestressed pile is simply embedded in the cast-in-place pile cap. Both experimental and analytical results are presented. It is shown that the plain embedment can develop the flexural capacity of the pile without distress to the pile cap of connection region provided that a sufficient embedment ...

Lecture 24 – Prestressed Concrete

Pre-tensioned concrete is almost always done in a precast plant. A pre-tensioned Prestressed concrete member is cast in a preformed casting bed. The BONDED wires (tendons) are tensioned prior to the concrete hardening. After the concrete hardens to approximately 75% of the specified compressive strength f’ c, the tendons are released and axial

Precast R.C. slabs are gaining an acceptance as a structural element for bridges. One of the difficulties in the construction using the precast R.C. slabs is an introduction of longitudinal prestress. Prestressing with internal cables is not practical for the precast concrete slabs because there exist transverse joints between each precast slab. On the other hand, longitudinal prestressing ...
