The dynamic loading tests of reinforced concrete members were executed and the effects of loading rate and hysteresis of deformation on the restoring force characteristics were investigated. From the test results the empirical formula is presented which predicts the dynamic restoring force characteristics by the use of the static restoring force under the same hysteresis of deformation. Based on the seismic response analyses, which were executed using the predicted dynamic restoring force and the static restoring force, it is shown that the plastic drift of the displacement response of structures is amplified and the possibility to cause the incremental collapse is increased by the effect of loading rate. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
