STUDY OF THE DISTRIBUTION OF PRESTRESSING UNDER ANCHORAGE (NORMAL AND LIGHTWEIGHT CONCRETE)
| 项目名称： | STUDY OF THE DISTRIBUTION OF PRESTRESSING UNDER ANCHORAGE (NORMAL AND LIGHTWEIGHT CONCRETE) |
| 摘要： | THE AIM OF THE RESEARCH IS TO STUDY FISSURATION PHENOMENA WHICH, IN STRUCTURES COMPOSED OF SEGMENTS SUCCESSIVELY CAST IN-SITU, OCCUR ALONG PRESTRESSING CABLES IN THE VICINITY OF THE ANCHORAGE AND WHICH RESULT IN THE DISTRIBUTION OF THE ANCHORAGE FORCE IN YOUNG CONCRETE. TWO TYPES OF CRACK ARE GENERALLY OBSERVED: - CRACK FOLLOWING THE CABLE AXIS AND APPEARING AT A CERTAIN DISTANCE IN FRONT OF THE ANCHORAGE. IT GENERALLY REMAINS FINE IF THE PRESTRESSED ELEMENT CONTAINS SUFFICIENT TRANSVERSE REINFORCEMENT; - CRACKS RADIATING IN FRONT OF THE ANCHORAGE, WHICH CAN SOMETIMES BE OPEN. |
