TRANSMISSION LENGTH OF PRESTRESSED WIRES IN CONCRETE B 55 |
摘要: |
THE TRANSMISSION LENGTH OF APPROVED PROFILED AND RIBBED PRESTRESSING STEELS IS TO BE DETERMINED BY MEANS OF PULL-OUT AND BEAM TESTS FOR HIGH CONCRETE STRENGTHS (B 55). BY MEANS OF THE BASIC BONDING LAWS DETERMINED BY THE PULL-OUT TESTS THE TRANSMISSION LENGTHS ARE TO BE COMPUTED ACCORDING TO DAFSTB/ISSUE 288 FOR THE POSITIONS "BELOW", "ABOVE" AND "BELOW AND ABOVE". TWO BEAM TESTS (DETERMINATION OF TRANSMISSION LENGTH BY MEASUREMENT OF CONCRETE DEFORMATION) ARE TO BE USED TO CALCULATE THE RELATION BETWEEN THE DEFORMATIONS MEASURED DIRECTLY ON THE BEAM AND THE VALUES COMPUTED FROM THE RESULTS OF THE PULL-OUT TESTS, FOR HIGH CONCRETE STRENGTHS. |
