ACTIVATION ENERGY OF CREEP OF CONCRETE UNDER SHORT-TERM STATIC AND CYCLIC STRESSES
A theoretically derived relation which has previously been shown by other authors to agree well with static creep is extended and transformed so that cyclic creep can be related to static creep as a function of the range of stress and time. Experimental results for periods under load up to 160 h show excellent agreement with the theory. The time dependence of the relation between cyclic creep and static creep is unclear from the short-term data used, but long-term data should clarify the function. With the relation fully defined, it would be a useful extension to the methods of predicting creep given in a number of codes of practice. /Author/TRRL/
