Structural Health Monitoring System for Wooden Houses as a Suitable Risk Communication Tool for Inhabitants

日本各地采用了多种木结构体系，这给木结构房屋的地震诊断带来了困难。在这种情况下，房屋的诊断方法是依靠诊断技术人员的知识和经验进行主观评价。通过微震分析，提出了客观评价房屋老化和地震等自然灾害破坏对房屋抗震能力下降影响的可行方法。

Many kinds of structure systems on wooden houses have been adopted throughout Japan, which brings the difficulty of seismic diagnosis for wooden houses. Added to this situation, the method of diagnosis for houses is subjective evaluation that depends on diagnostic technicians' knowledge and experience. We proposed the feasible manners to objectively estimate the effect on the deterioration of earthquake-resistant capacity of houses caused by aged deterioration and/or damaged by natural hazards such as earthquakes through the microtremors analysis.
