EXECUTION OF LARGE-SCALE TESTS TO DETERMINE MATERIAL CHARACTERISTICS DURING THE DISMANTLING OF A PRESTRESSED CONCRETE BRIDGE (MOTORWAY NEAR VIENNA)

项目名称：	EXECUTION OF LARGE-SCALE TESTS TO DETERMINE MATERIAL CHARACTERISTICS DURING THE DISMANTLING OF A PRESTRESSED CONCRETE BRIDGE (MOTORWAY NEAR VIENNA)
摘要：	WHEN THE PRESTRESSED CONCRETE BRIDGE CONSTRUCTED IN 1950-51 IS PULLED DOWN, MATERIAL TESTS ARE TO BE CARRIED OUT IN ORDER THAT CONCLUSIONS MAY BE DRAWN AS TO THE BEHAVIOUR OF PRESTRESSED CONCRETE STRUCTURES AND THE CONSEQUENCES FOR FUTURE DESIGN AND CONSTRUCTION OF PRESTRESSED CONCRETE BRIDGE STRUCTURES. THE PROJECT COMPRISES: (1) REMOVAL OF THE PRESTRESSING MEMBERS AND MEASUREMENTS OF THE PRESTRESSING FORCES; (2) REMOVAL OF SLACK REINFORCEMENT BARS AND DETERMINATION OF FATIGUE STRENGTH AND TENSILE STRENGTH; (3) CORE EXTRACTION FROM AREAS WITHOUT PRESTRESSING ELEMENTS AND DETERMINATION OF CYLINDER COMPRESSIVE STRENGTH AND SPLITTING TENSILE STRENGTH; (4) CORE EXTRACTION FROM THE BRIDGE DECK TO CHECK EXPERIENCES ON THE EFFECT OF DE-ICING SALTS; AND (5) TESTS ON PRESTRESSING STEELS AND INJECTION MORTAR.
