| Outline of Final Research Achievements |
A RC school building was moderately damaged by the 2007 Chuetsu-oki Earthquake. The anticipated design failure modes of most of the columns of the building were flexure, although most of the columns actually failed through shearing. The static loading tests for varying lengths of cutoff bars and presence of spandrel walls were conducted. The conclusions derived from these tests were that the deformation capacity of a column with cutoff bars degraded tremendously under the conditions that the yielding hinge was located at the cutoff point, the diagonal cracks generated from the cutoff point were inclined at approximately about 50 degrees and the effect of the presence of spandrel walls on deformation capacities was small. The structural models with various conditions of cutoff bars and spandrel walls were used in earthquake response analysis. The residual seismic capacity ratio of the model is close to the residual seismic capacity ratio of the real damage of the building.
