Abstract:

To define the norms of the special mechanical anchors and direct the design and the construction of hybrid bonded fiber reinforced polymer(HB-FRP), the specimens were investigated in a drawing test program in order to study the anchor depth of screw bolts. The finite element analysis was conducted to simulate the contact compression stress on the basis of different sizes of steel plate and bolt prestress by the Pretension 179 element and compact pairs of ANSYS. On the basis of experiments, the formula for calculating anchor depth of screw bolts is put forward. A method was suggested to guide the designs and the choice of the steel plates on the basis of the finite element analysis. It contributes to direct the design and the construction of HB-FRP.

Key words: fiber reinforced polymer (FRP), screw bolt, strengthening technique, anchoring parameter
