Probabilistic Design Approaches of Centrifugally Cast Concrete Structures in Telecommunications Infrastructure

Telecommunication masts and towers, widely used in communication and power transmission systems, are exposed to external environmental actions. Dynamic loads can cause extreme stresses and even structural failures. The research examines several structural systems consisting of a centrifuged concrete core with a circular cross-section, guy wires, tension ties and strut elements. Such a system allows for reduced bending moments, effective buckling length and ensures more efficient use of materials compared to traditional tower and mast systems. The article presents a reliability analysis of a centrifuged concrete core with a circular cross-section, based on probabilistic calculations, including the Monte Carlo simulation, to assess the safety of structures under extreme wind loads. The results of the study show that the proposed structural system with centrifuged concrete and additional tension members are more rational and durable compared to traditional telecommunications structures. By applying probabilistic assessment and structural analysis, it is possible to assess the resistance of structures to extreme loads and optimize their design and operation.
