Abstract: Based on the bond effect, friction effect and bend effect of the mechanism of a wave-shaped-teeth (WST) anchor, many kinds of anchors are designed. Many tests which are composed of many layers carbon fiber reinforced polymer (CFRP) sheets and those anchors are pulled. Those pull experiments quantify the parameters of the anchor length formula. At the same time, the WST anchors with bond and without bond to anchor CFRP sheet are tested. Test results indicate that the frictional force (the axial force increment of the first row bolt in the WST anchor brings this frictional force) firmly anchors CFRP sheet. And this paper suggests that when the bolts are designed, the axial fore and shear fore of the bolt in the WST anchor are the certain percent of ultimate tensile strength of CFRP sheet.
