This paper presents straightforward sensitivity assessment of a telecommunication tower. The analysis is set toidentify the elements of the tower which may be reinforced with the greatest structural advantage. As current expertopin ions on structural redesign of similar structures due to a planned addition of extra loads are mainly based ondeterministic computations or engineering intuition, the probabilistic-based approach is proposed to verify andsupplement the reinforcement design projects, in contrary to the existing action course. In the paper, the analysis isperformed on an example of a standard, spatial telecommunication truss tower subjected to a standard set of loads,special attention is paid to wind and icing load. The cross-sectional areas of curbs and braces of each tower segment areadopted as random variables of the problem, in the form of sets of percentage increments of the initial cross-sectionalarea values. Joint impact is observed of individual variable change and the change imposed by groups of key variableswith a similar impact on the structural load capacity. Finally, engineering-oriented conclusions are presented, ofprobabilistic origin. A beneficial solution of the reinforcement is proposed, maintaining the reliability of the initial tower.
