In recent years, the use of helical anchors for guyed transmission towers has increased
considerably in Brazil. This type of structure is subjected to important environmental cyclic
loadings, but their effects are typically ignored in the design process. Under this scenario,
this paper presents the preliminary experimental results of an investigation of the cyclic and
post-cyclic monotonic responses of a single-helix anchor in very dense sand. Three different
combinations of high-level loading cycles, simulating the effects of high wind speeds on the …
