ASSESSMENT OF TRANSMISSION OF THE SHEAR STRESS IN POTTED ANCHORS FOR COMPOSITE RODS 3. BIPOTTED ANCHOR

摘要

Our previous investigation into the means for decreasing the peak interfacial shear stress in bond-type anchors for fiber-reinforced polymer rods [1, , 2] is extended to include the case where the bonded length of the rod is divided into two regions, each having a potting material with a different elastic modulus. Based on the analytical model developed earlier, a detailed parametric analysis of the influence of such parameters of a bi potted anchor as the relative lengths of anchorage zones and the pottant moduli is carried out for two schemes of anchor loading.
