Abstract

Single-pole towers are used in engineering practice when there is not enough land to construct a conventional four-leg transmission tower. The load-bearing mechanism of the single-pole tower foundation system is quite different to the conventional type, which is subject to moment loads. Half-scale model experi- ments were conducted first using the same type of anchorage method between a single pole and reinforced concrete foundation. Two cases with different thickness of reinforced concrete cover were studied, and the re- sults indicate the significance of the confinement effect on such anchorage systems. Finite element analyses were then conducted and successfully simulated the experimental results. Based on the understanding of fail- ure mechanisms, which were studied both experimentally and via numerical analysis, a simplified design is proposed for the primary stage of the design.
