A Fundamental Study on Measurement Method of Plastic Heat Generation and Thermal Analysis of Buckling Restrained Knee Brace with the Wood

It is necessary to survey the damage state of buildings after an earthquake disaster, but the current damage evaluation method takes a lot of time and efforts. Also, the experts who went to the site are suffered by aftershocks. So, in recent years, structural health monitoring using accelerometers and other devices has also been developed, however, there are also issues such as the difficulties of assessing the member-based damage. Therefore, a new damage evaluation method using plastic heat characteristics of steel under inelastic behavior is proposed. In the previous study, the damage evaluation method by temperature measurement using the plastic heating in steel material can be used to assess the damage at the frame in global. 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 actual 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.
