This paper presents an experimental study for the investigation of the effect of the circumferentialcrack caused by impulsive uplift load on the dynamic lateral resistance of reinforced concrete (RC) column. First, the impulsive uplift test was carried out for the miniature RC column model (10cm square section and 30cm height), and the horizontal circumferential crack was occurred in the specimen. Second, the horizontal static and high speed (2.0m/s) loading tests were executed in order to examine the lateral resistance of damaged specimen and compared with no-damaged specimen, respectively. The experimental results show that the circumferential crack due to impulsive uplift load reduces about 10-17% on the lateral resistance and about 15%-, 40% on the lateral deformability of RC column.
