抄録
An experimental study is made to investigate the effects of a strain rate on fundamentalmechanical properties of component materials of reinforced concrete structures subjected toearthquake load, those are concrete and steel reinforcing bars. Load is applied monotonicallyor cyclically to a specimen under the prescribed strain rate. Range of strain rates in caseof dynamic loading is 0.005/sec to 0.1/sec. Compressive strength of concrete increaseswith increasing strain rate. However, a geometrical configuration of a stress-strain curveand the strain at the maximum stress are hardly affected by a strain rate. From tension tests ofsteel bars, it is observed that yield stress increases with increasing strain rate. The behaviorin the strain-hardening region and the strain at breakage are not affected largely by a strainrate. There is no significant difference between the stress-strain curves under monotonicloading and the envelope curves under repeated loading.
