Design of Multi-Level Guyed Towers: Wind Loading

Abstract

In recent years the needs of the television industry, of national defense, etc., for towers of great height has resulted in a great increase in the construction of multilevel guyed towers (Fig. 1). By supporting the structural shafts at suitable intervals with high strength wire strand guys, a highly economical structure results when space is available to provide adequate anchors for the guys at ground level. Although most multilevel guyed towers in this country have trussed structural steel shafts of triangular cross-section- as shown in Fig. 2, others have been built as square box trusses, circular shafts of steel plate or concrete, and timber box trusses.
