Fatigue Failure Criterion of Concrete under Multi-axial and Variable-amplitude Cyclic Loading andIts Application in Offshore Engineering

摘要

The fatigue tests of concrete have been conducted with constant confinedrnstress, including constant- and variable-amplitude fatigue loading. Thernresults of the fatigue tests indicate that the fatigue reduction coefficientrnchanges with constant confined stress. Through the analysis of the testrnresult, the failure criterion of concrete under multi-axialrnvariable-amplitude fatigue loading has been established.
