Abstract:
Earthquake response tests on a full scale seven story R/C building structure were carried out by employing an equivalent single-degree-of-freedom pseudo-dynamic test method. First, the structure without nonstructural elements was tested from small magnitudes of response (elastic range) to large response (heavy damaged range). Second, the damaged structure was repaired and strengthened, and nonstructural elements were installed . After this, the structure was tested by the same test procedure as that used for the original tests . This paper presents the responses, the restoring force characteristics, and the observed damage obtained during the tests before and after the repair work. This paper also presents the dynamic characteristics obtained through vibration tests.
