AB - An experimental study was conducted to understand the cyclic behavior of circular steel tubes embedded at the bottom of a wind tower and evaluate the suggested design criteria for required minimum embedment length of the steel tubes. Three circular steel tube - concrete foundation anchorage specimens were designed and prepared for the study. The only difference among the three was the embedment length of the steel tube. The embedment length of the first specimen (SP1) was calculated from the method suggested in this study. The second specimen (SP2) and third specimen (SP3) were designed and tested to investigate the cyclic performance of the anchorage that had a shorter embedment length than that of SP1. A test setup was prepared so that cyclic lateral displacements could be applied at the top of the steel tube structure. No axial loads were applied on the top of the steel tube structure. Based on experimental observation and strain analysis, several conclusions were drawn and suggestions for future study were made.

An experimental study was conducted to understand the cyclic behavior of circular steel tubes embedded at the bottom of a wind tower and evaluate the suggested design criteria for required minimum embedment length of the steel tubes. Three circular steel tube - concrete foundation anchorage specimens were designed and prepared for the study. The only difference among the three was the embedment length of the steel tube. The embedment length of the first specimen (SP1) was calculated from the method suggested in this study. The second specimen (SP2) and third specimen (SP3) were designed and tested to investigate the cyclic performance of the anchorage that had a shorter embedment length than that of SP1. A test setup was prepared so that cyclic lateral displacements could be applied at the top of the steel tube structure. No axial loads were applied on the top of the steel tube structure.
