It was attempted to evaluate the seismic performance of an old medium-rise R/C residential building. The building constructed in 1963 consists of varieties of brittle columns. Collapse tests were conducted for half-scale models of the columns. And based on the test results, the seismic behavior of the building including post-peak regions was studied. The study has revealed that 1) as far as ground motions with maximum velocity of 50cm/s are considered, the amplitude of inter-story drift angle remains as small as 0.7% due to short period and high strength of the building, but 2) if ground motions with maximum velocity of 75cm/s are considered, it increases to 6% due to the severe strength deterioration that the columns undergo.
