The purpose of this thesis is to study the complete design for
a circular prestressed concrete tank and the application of the principle of dynamic analysis to the design of the tank structure. A
proposed method of circular prestressing is presented and the
comparative study of the prevailing circular prestressing system
is also included.
The thesis is divided into four parts. The first part is a study
of the structural analysis using the theory of the thin shell as an
approach and the prestressed concrete design. The second part
presents the proposed zig-zag extensioning method of circular pre-stressing. Numerical examples for the complete design procedure
follow as illustrations. The third part makes a brief review on the
dynamic analysis for the tank structure due to the earthquake disturbances
In this section, only the application of an approximate
energy method is discussed. The fourth part of this thesis is the
comparison between different methods of circular prestressing
including the Preload method, Mag1el-Blaton method, Freyssinet cable method
Precast method, and the Zig—zag extensioning method. Several
construction problems are discussed.
