13.1 Introduction
Circular prestressing refers to the process of prestressing circular structures like pipes and tanks in which tendons are wound in circles. But linear prestressing indicates all other types of prestressing where the tendons are straight or curved, but not wound in a circular shape. Most often in the case of prestressed concrete circular structures, prestressing is done in both circumferential (circular prestressing) and longitudinal (linear prestressing) direction. The design of some typical prestressed circular structures like pipes, water tanks and domes are briefly covered in this chapter.
13.2 Circumferential Prestressing
The prestress in the circumferential direction is designed to resist ...
