Outline of Final Research Achievements

The seismic performance of the non-structural elements was assumed to be directly supported by the structural frame in previous research. On the other hand, few studies of non-structural elements were focused on the performance with the effect of supporting structure. This study focuses on cases where the partition wall is partially supported by the other elements, and the study aims to examine the effect of supporting structures on the performance of partition walls through the experiments.
First, actual examples of the supporting structures of partition walls and the standard specification are investigated and extracting experiment target. Second, the vibration table tests and the static loading tests are conducted for the partition walls supported by suspended ceiling with steel furring on the upper part. From the results, the response characteristics of the walls are obtained and compared with the results for the case with supported the structural element directly.
