Abstract |
As the structural type of apartment houses has been changing from wall column structures to Rahmen structures, demand for lightweight walls has been increasing. Although lightweight walls reduce self-weight of the building and enable efficient use of interior spaces, to apply them as building walls, the structural safety of them should be secured without fail. The lateral load resistance test method and impact resistance test method for the verification of lightweight walls’ structural safety have not yet been established. The purpose of this study is to standardize lateral load resistance test method, impact resistance test method using large soft body, and impact resistance test method using small hard body. Most of the configuration of the test methods and testing device were made by modifying the content of BS 5234:1992. However, the conditions of loads applied to specimens were reestablished reflecting the characteristics of loads acting on actual walls. In the lateral load resistance test, load conditions were divided into three levels; 500N, 1000N, and 3000N so that the conditions could be selected and applied according to the uses of walls. In the impact resistance test using large soft body, the length of the rope was set to be at least 2.5m and the drop heights were divided into three levels; 200mm, 400mm, and 600mm. In the impact resistance test using small hard body, the drop heights were divided into three levels; 0.1m, 0.2m, and 0.5m. The performance test methods standardized in this study will be objective evaluation tools when optimum lightweight walls are designed or selected in construction sites. In addition, they will be usefully utilized when setting performance goals for development of new lightweight walls. |
