Popis:	This paper describes forced vibration tests and microtremor measurements performed at 4-story RC building before and after 4-walls were damaged artificially. The dynamic characteristics change is investigated using these measurements data. It is shown that (1) The damages can be clearly detected from changes of resonant frequency and amplitude between stories based on forced vibration tests; (2) The damages can be detected from change of resonant frequency, but that can not be detected from change of response magnitude factor based on microtremor measurements.
