Connection Strength of Undercut Anchorage Stone Cladding

Abstract

Abstract Experiments were conducted on seventy-two stone panels to investigate the connection strength of undercut anchorage stone cladding. The following factors were considered in this study: the stone type, the distance between the hole center and the edge of the plate, the hole depth and the diameter and type of the undercut anchor. The results show that the stone type and anchor depth are the factors that most strongly influence the anchorage strength. The distance between the hole center and the edge of the plate are secondary factors. The connection strength increases when the distance between the hole center and the edge of the plate from 40 mm to 60 mm. The anchorage strength of percussion anchor is approximately 10% higher than that of a screw-in anchor under the same conditions.
