| Abstract | The matrix method of structural analysis using stiffness
coefficients was used to solve for the tower displacements, the
stresses in the structural members and the critical wind load that could cause structural instability in a guyed tower. The structure was represented by a beam-column on non-linear elastic spring supports. The non-linear characteristics of these elastic spring supports are the horizontal reaction, the vertical reaction and the concentrated moment. These reactions were obtained from the guy analysis by assuming a parabolic shape for the guy. A successive approximation method in the numerical procedure was used to evaluate the buckling factor of the tower for any specified wind load. The buckling loads obtained from the numerical
method and the stiffness method agreed fairly well. An experimental investigation was conducted for a six-guy level
tower model with a four-guy system. Horizontal loads were applied at the guy points along the guy plane. The theoretical values of the shaft displacements, the stresses in the structural members and the predicted buckling load agreed fairly well with the experimental
results. |
