  • Recently there are many attempts to introduce PC construction method in buildings. But the study on PC structural wall has been made progress so slowly because it is very difficult to develop new items. In this study, we have developed new vertical joint on PC wall in order to upgrade constructivity and structural performance of the existing connections, then we have evaluated the seismic resistance performance. As a result of the cyclic loading tests for two specimens, proposed vertical joint on PC wall has shown that it behave the excellent structural performance in comparison to PC wall having no joint. Therefore, we think that proposed vertical joint is the system to apply buliding structure.
