Abstract
In order to understand failure mechanisms of existing non-conformed reinforced concrete buildings during a severe earthquake, shaking table and static tests of a full-scale RC frame were conducted. A specimen of the RC frame was designed based on the building regulation that had used before 1971,under which an amount of shear reinforcements of columns was less than that under the current regulation. Several ideas to design a loading apparatus for the shaking table tests were taken into consideration to simulate the dynamic behaviors of the RC frame as a part of a whole structural system. The test results indicate that the existing non-conformed RC buildings have a high possibility of shear failure in columns.
