Abstract
The dynamic analysis of a guyed mast subjected to strong turbulent winds is complicated by the nonlinear structural properties of the system and by the random nature of the wind load. Because of the significant differences between static and dynamic response characteristics, conventional static analysis methods can lead to unsafe designs. The new British Standard BS 8100 Part 4 for guyed masts has adopted two static analysis methods for estimating dynamic response: a simplified gust response factor method for shorter masts, and a more general patch load method for masts of all sizes. The Code methods simplify dynamic response calculations while overcoming deficiencies present in earlier static analysis methods. Results from a comprehensive calibration study indicate that the Code methods give reliable results for masts designed in accordance with good engineering practice.
