DESIGN PRINCIPLE USED FOR THE FOURTH DANUBE BRIDGE IN VIENNA: SPAN-BY-SPAN CONSTRUCTION OF CONTINUOUS GIRDERS /IN GERMAN/

A DESIGN PRINCIPLE IS DESCRIBED THAT PERMITS THE CONSTRUCTION OF A PRESTRESSED CONTINUOUS BEAM IN INDIVIDUAL SPANS IN SUCH A WAY AS TO PRECLUDE THE OCCURRENCE OF ANY REDISTRIBUTION DUE TO CREEP. THIS IS ACCOMPLISHED BY MEANS OF A TENSIONING STRAND ARRANGEMENT RESULTING IN MOMENTS OF REDISTRIBUTION WHICH ARE EQUAL AND OPPOSITE TO THE MOMENTS ABOUT THE POINTS OF SUPPORT RESULTING FROM THE WEIGHT OF THE STRUCTURE. THE EFFECTS OF CREEP ARE THUS RESTRICTED TO THE INFLUENCE EXERTED BY THE LOSS OF PRESTRESSING FORCE. /TRRL/A/
