| Summary: | In order to understand the behaviour of steel members retrofitted using adhesively bonded fibre
reinforced polymer (FRP) plates, the bond slip characteristics of the adhesive joint between the FRP and
steel must first be established. This is important so that debonding does not occur whilst the members
are in service. Previously, purely empirical research on establishing the bond slip characteristics involved
strain gauging the length of the FRP plate, which can lead to a major scatter of results as well as
underestimating the peak shear stress. The subject of this paper is to describe a technique for quantifying
the bond slip characteristics based on a structural mechanics approach and which does not require strain
gauging the plate. Two types of pull tests and a partial-interaction numerical model are used to quantify
the major characteristics of the bond slip and two types of adhesive are used to illustrate the approach. |
