Five drilled shaft pier models, each having two anchor bolts, were tested to verify scale effects in a combined achorage stress condition. A geometic scale factor of 8 was adopted as a practical minimum. The failure patterns and general behavior were very simliar to those of well-documented full size protoype specimens. It was concluded that reduced scale models could be effectively used in anchorage studies invovling complex combined stress conditions if several full size specimens are also tested.
