The effects of tapered sleeve in improving the achorage bond of reinforcement bar

This research examine on the effectiveness of tapered sleeve connector in providing confinement effect to embedded reinforcement bar. The objectives of the investigation are to study the bond mechanism of grouted sleeve connector and to study the effects of confinement provided by the grouted sleeve...
