INVESITIGATION AND EXAMINATION OF DAMAGE CONDITIONS OF OLD REINFORCED CONCRETE BUILDINGS DUE TO SUBSIDENCE AND THE EFFECT OF DAMAGE CONDITIONS ON SEISMIC PERFORMANCE OF THE BUILDINGS

本文介绍了老旧钢筋混凝土建筑沉陷破坏情况的调查和检查，并讨论了这种破坏情况对结构抗震性能的影响。对11个模型框架和8个考虑自应变损伤的抗震墙进行了试验，并结合既有建筑框架的试验结果，考察了损伤对结构抗震性能的影响。这些研究为既有钢筋混凝土建筑抗震性能的判断提供了有用的数据。

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.
