Non-Linear Dynamic Analysis of Guyed Towers to Wind Loading
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 1
Abstract
A nonlinear deterministic approach for predicting the wind response of guyed towers is described in this paper. The nature of wind, static and dynamic wind effect are defined. In the present approach, the time space history of wind is simulated and fed into the system's equations of motion. These are integrated in the time domain and the response of the guyed tower is obtained. Linear and non-linear response of a guyed tower are evaluated to simulated wind histories by a multi-regressive technique. In addition, comparative studies have been performed on the tower in order to check the effect of wind velocity and roughness length on their response. A comparison of mean and dynamic responses and a discussion of these results relative to the quasi static analysis are presented.
