Abstract:
The results of a pilot project examining the cyclic uniaxial stress-strain behaviour of Grade 500 reinforcing bars that satisfy the requirements for N-type steel in AS4671 are presented in this paper. The type of test conducted includes a monotonic test, a cyclic test recommended in the draft ISO standard for mechanical splices on reinforcing bars in earthquake situations, a cyclic test with large strain reversals primarily on the tension side, and a cyclic test with large symmetrical strain cycles. These initial tests were intended to pinpoint the important parameters that need to be studied in more detail. A series of comprehensive, statistically valid tests will follow.
