Stress-deformation analysis of the high voltage transmission tower
 Kuběna, Tomáš ; Pokorný, Jan (referee) ; Fuis, Vladimír (advisor)
The thesis deals with the analysis of a high voltage power pole near the village Lešná, whose collapse will cause an outage of the electricity network in the area. The model of the pole was created on the basis of drawings provided by Arpex Moravia s.r.o. The pole is designed as a truss system using the general node method, subjected to the weight of the structure, wind and the weight of live conductors. The analytical calculation is performed in Matlab and then verified by numerical calculation in Ansys Workbench. When the pole is subjected to all previously mentioned loads, the maximum deformation has a magnitude of u_max=18.89 mm, which is mostly affected by the wind action. The resulting safety to elastic limit state is k_MSP=23.95. The pole is operated with sufficient safety and collapse will not occur under normal operating conditions.
