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.
