| Research Abstract |
Cyclic loading tests of reinforced concrete member fails in flexural yielding were conducted to study hysteresis and mechanism of damping. The experimental test results showed that hysteresis damping between before flexural yielding and after was greatly affected by deterioration of bond between steel rebar and concrete. Equivalent damping factor obtained from the test result was increased as the margin of ultimate bond strength between steel rebar and concrete to design bond strength was increased.
