Abstract

AbstractTo find an alternative way of improving bonding and restricting sliding displacement, a new technique that combines fiber-reinforced polymer (FRP) surface adhesion [externally bonded FRP (EB-FRP)] with a new type of mechanical fastening, namely hybrid bonding (HB-FRP), is developed. The beam specimens are investigated and compared in a new modified beam-shear program to examine the bonding behavior of HB-FRP and EB-FRP. The finite element analysis is conducted to simulate the interfacial shear on the basis of different bolt pretension force by Pretension 179 element and compact pairs of ANSYS software. Also the anchoring parameters of the hybrid bonding of FRP are studied by a drawing test program to study the anchor depth of screw bolts and by the finite element analysis to simulate the contact compression stress on the basis of different sizes of capping plate and bolt pretension for the selection of the capping plates and bolts. On the basis of experiments and the finite element analysis, the f...
