CUMULATIVE STRENGTH INDEX DISTRIBUTION ALONG BUILDING HEIGHT AND STORY COLLAPSE RATE IN REINFORCED CONCRETE BUILDINGS
The seismic evaluation guideline of existing reinforced concrete (RC) buildings is provided by The Japan Building Disaster Prevention Association (JBDPA 2001). A study on effects of a cumulative strength index, CT, distribution along the building height on story collapses in RC buildings was examined. The analytical results of models were mainly discussed by the story collapse rate and the strength ratio that is newly defined as the ratio of CT index of weak story to average of CT index of all the stories in a building. The strength ratio which leads to story collapse was presented by dynamic response analyses results. However, in case of the weak-beam-strong-column designed structure, even if the strength ratio is not ideal, the story collapse will not occur due to total beam yielding mechanism
