A laboratory model tests has been carried out to measure the ultimate load of vertically embedded cylindrical anchors in sand. For the model test, a dimensional analysis of a general anchors was performed. Details of the dimensional analysis of in-situ anchors were presented in this paper. Based on the results of the dimensional analysis, the model-scaled anchorage system was simulated. Anchor model tests were performed on two types of model anchors. One has been shaft and end plate, called composite anchors, the other has been only shaft. Due to the extended plate of the anchor shaft end, both the shaft friction and the end resistance have substantial contribution to the pullout capacity. The pullout load was applied to the bottom of the model anchor through a high strength steel rod of 4mm diameter. Each ultimate loads were measured and compared with the design load.
