Guyed Latticed Communication Towers are highly complex structures which are very difficult to model and analyze. Because of their geometric non-linearity, P-D effects are significant. To evaluate this, a sample guyed tower with one set of guys was modeled and linear and non-linear analyses were carried out to show the effect of P-D. Because of P-D effect, the moments are magnified by 1.29. The results show clearly that P-D effect cannot be ignored. Three representative guyed towers of 76.8 m (252 ft), 212 m (697 ft) and 583 m (1914 ft) height with four, five and nine guy levels respectively were included in the investigation. The difficulties encountered in analyzing these three towers under realistic loadings are discussed. The sequence of application of loads required for the successful analysis of these towers was determined.* *This dissertation is a compound document (contains both a paper copy and a CD as part of the dissertation).
