TENSILE CAPACITIES OF CFRP ANCHORS

, 2006
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.
