Abstract
The present research work deals with the nonlinear structural behavior
of the guyed towers The thesis starts with an introduction including the
description of the different types of guyed towers, uses of them and their
advantage. Also a summary of the present work is presented.
A historical review and a literature survey of the methods of analyzing
single inclined guy cables and the method of static and stability analysis of
guyed towers have been presented.
The nonlinear static analysis of the guyed tower by the energy method
is explained and the stability finite deflection theory is applied to take the
effect of the axial force on the mast. The method for determining the critical
buckling loads is illustrated and a non dimensional shear stiffness factor
called CPF which represents the elastic critical load is introduced.
A recommendation for the analysis and design of the guyed tower
according to lASS recommendations is presented, which contains the
principles of the analysis, the design procedure and the kind of loads acting on
the guyed towerThe present research work deals with the nonlinear structural behavior

according to lASS recommendations is presented, which contains the
principles of the analysis, the design procedure and the kind of loads acting on
the guyed towers.The method of analysis is applied to three existing guyed towers
erected in Egypt.The analysis is carried out using a computer program by the
energy method and including the effect of the axial force on the mast by the
finite deflection theory .The effect of some parameters and the effect of the
shear stiffness factor CPF on the critical buckling load are investigated. The
results are illustrated in curves and tables which help the designer to perform
economic and efficiency design for the guyed towers.
