Özet

In reinforced concrete buildings inserting adequate amount of reinforced concrete infills is an effective strengthening technique. Another promising technique is to strengthen the existing hollow clay tile infill with diagonally placed CFRP sheets. In this technique, CFRPsheets are extended to the frame members. The connection between CFRP sheets and frame members is provided by CFRP anchors. If an adequate amount of CFRP anchoring is used, CFRP applied hollow clay tile infill becomes a unique part of the reinforced concrete frame. Thus in this strengthening technique, the effectiveness is dictated by the CFRP anchors. In this study, by means of the prepared test setup, the pull-out strength capacities of CFRP anchors are measured. The effects of concrete compressive strength, anchorage depth, anchorage diameter, and number of fibers on the tensile strength capacity of CFRP anchor are studied.
