EFFECTS OF CREEP, SHRINKAGE AND TEMPERATURE ON HIGHWAY BRIDGES IN THE UNITED KINGDOM

MEASUREMENTS OF SHRINKAGE, CREEP, AND TEMPERATURE MADE ON BRIDGES IN THE U. K. ARE DISCUSSED. IT IS SHOWN THAT THE MAGNITUDE OF THE THERMAL MOVEMENTS ON SETTING MAY WELL EXCEED THAT DUE TO THE SHRINKAGE ARISING LATER FROM MOISTURE LOSS. THE CREEP FACTOR TO DIN 4227 HAS BEEN FOUND TO BE IN THE RANGE 1.0 TO 2.0 AT 10,000 DAYS, AND THE TOTAL MOVEMENT PROPORTIONAL TO THE LOGARITHM OF TIME. CORRELATION HAS BEEN ACHIEVED BETWEEN SMALL SPECIMENS AND THE STRUCTURE BY PARTIALLY WATERPROOFING THE SPECIMENS. THE RANGE OF THERMAL MOVEMENT IN BRIDGES IS DESCRIBED AND IT IS SHOWN THAT THERMAL STRESSES ARE SOMETIMES COMPARABLE WITH STRESSES DUE TO LIVE LOADS. /TRRL/
