2016年熊本地震后，采用微震测量和目测方法对80栋两层轻钢结构受损房屋进行了调查。通过微震测量，分析了房屋固有频率与建筑面积平均位移响应谱（0.2 ~ 0.3秒）的关系。结果表明，随着位移响应谱的增大，房屋的固有频率减小。
After 2016 Kumamoto Earthquake, we investigated 80 two-storied damaged houses of light-gauge steel structure by microtremor measurement and visual check. We analyzed the relationship of natural frequency of the houses by microtremor measurement and average displacement response spectrum (0.2 〜 0.3 seconds) of construction area. As a result, natural frequency of the houses decrease as the displacement response spectrum increase.
