| Research Abstract |
This report describes the investigation and examination of damage conditions of old reinforced concrete buildings due to subsidence, and the influence of such damage conditions on the structural seismic performance was discussed. And tests of 11 model frames and 8 earthquake resisting walls considered the damages due to self-strain stresses had been done, and more the influence of the damages on the structural seismic performance was examined by using the test results of existing building frame. The useful data for judgment on seismic performance of existing reinforced concrete buildings was got by these studies.
