FATIGUE PROPERTIES OF TEMPCORE REINFORCING BARS

Constant cycle fatigue tests were carried out on Australian manufactured Tempcore reinforcing bar. The main variables in the tests were the maximum and minimum stress levels in the load cycle. Fatigue life was found to depend on stress range, defined as the maximum stress level minus the fatigue limit corresponding to the minimum stress level. This definition of stress range was found to be more useful, for correlation purposes, than that of maximum stress level minus minimum stress level. A simple equation which can be used to estimate fatigue life from the stress range was developed from the data. Comparisons with several fatigue tests conducted on Australian made cold worked reinforcing bars suggest that the fatigue properties of Tempcore are superior to those of the cold worked bars currently available, particularly in the severe low cycle, high load, range. The tests were very restricted in number and extent, and the conclusions are therefore tentative. (Author/TRRL)
