Abstract:
The present series of tests comprises about 100 tests specimens all of which had formerly been subjected to pulsating loads. The investigation is a direct continuation of the tests in (1) as the material left over from these tests was used in the present ones. The factors studied in (1) have become parameters also in this investigation together with those factors which are measured in normal static tests, i.e. yield point, breaking point and elongation. These measuring results have been compared with the static strength values of the reinforcing bar when unaffected by earlier load applications.
