Project description:
The task’s scope was the assessment of the bearing capacity of existing monopoles, which were installed in various rural areas of Cyprus. The monopoles were classified in two main categories according to their height, thus 18 and 24 m. The poles consist of individual 6 m circular hollow section members, interconnected via splice connections. Smaller section diameter was utilized for each part with respect to height. The analyses revealed that 18 m monopole has sufficient bearing capacity to withstand the imposed loads and so no strengthening measures were taken. Moreover, the performed analyses indicated that the superstructure’s members and the foundation of the 24 m monopole had adequate bearing capacity. Although, additional finite element analyses illustrated inadequate bending capacity in all the splice connections. Therefore, it was decided that the most profitable, applicable and less disruptive strengthening solution was the replacement of the existing splice connections’s bolts with bigger diameter hot-dip galvanized bolts.
