ResumoThe geometrically nonlinear dynamic response of a three-dimensional model of a guyed tower, when a selected guy suddenly ruptures, sending an impulsive shock to the entire structure is studied. The sudden rupture of a guy is simulated by the instantaneous removal of its end tension, applied as an external force at its mast attachment point. A 500 ft tall tower with three stay levels was analysed. The analysis was performed for a nominal wind speed acting in the plane of the ruptured guy, assumed to be a windward one. The mast was modelled by a three-dimensional space truss and the guys by three-dimensional elastic catenaries.
