| Outline of Final Research Achievements |
The damage process and the degree of collapse margin when traditional wooden houses are subjected to excessive strong earthquake ground motions are quantified and the target performance of seismic retrofit is clarified. Our research is based on field survey, experiments, and analyses. The main results are as follows. First, we develop nondestructive test methods of wooden members to identify the degree of degradation and the property of material. Next, we clarify the collapse limit of traditional wooden frames by many static loading tests. Then, we conducted field survey to clarify the structural characteristics and collapse margin of houses. Finally, we develop the design methods to grasp the collapse limit of traditional wooden hoses.
