END ANCHORAGE WITH POSTINSTALLED REINFORCING BARS: THE NEW TR069 DESIGN APPROACH

The use of post-installed reinforcing bars to connect existing concrete elements to newly cast concrete has increased significantly in the last decade. Very common applications are connections between reinforced concrete beams/slabs and columns/walls or reinforced concrete columns/walls and foundations. The design of such connections is clearly limited by the need to use straight reinforcing bars. The paper presents the new design approach introduced by the new EOTA Technical Report 069, which considers the actual bond-splitting performance of the adhesive. Some practical cases are presented to show the advantages and the drawbacks of the method.
