Abstract

It is necessary to survey the damage of buildings after an earthquake, but the current damage evaluation method takes a lot of time and effort. Also, the experts who went to the spot are suffered by aftershocks.To solve these problems, structural health monitoring using accelerometers and other devices has also been developed. But there are also issues such as the difficulty of assessing damage at the component level. Therefore, a new damage evaluation method using plastic heat characteristics of steel is proposed. In the previous study, the damage evaluation method by temperature measurement using the plastic heating in steel can be used to assess the damage at the structure level. Also, it is proposed to evaluate the damage of buildings by sacrifice components such as the knee brace to use this new damage evaluation method in real buildings. In this paper, for a fundamental study on the adaptability of measurement planning and analysis methods, a dynamic experiment and thermal analysis were conducted on a buckling restrained knee brace with the wood. The results show that the appropriate measurement method can be found and that the analysis results can be chased to the experimental results.
