Abstract—Accumulation of vibration and inclination data is important for health monitoring of building. If the condition of buildings can be monitored regularly and abnormalities is detected, damage of the building can be found. In this paper, two types of measurement devices were evaluated and compared to measure the condition of buildings. One is an inclination angle measurement device using a bubble tube and a camera. The other is a vibration and inclination measurement device using a MEMS type accelerometer sensor. Both methods can measure slight inclination angles of a building. The accelerometer can also measure vibration waveforms due to earthquakes and time variation of building vibration. The vibration and inclination angle of a mid-rise building were measured. Daily variations of the angle due to sunlight on the building, vibrations caused by human activity, and seismic waveforms were measured. It was found that the method using a bubble tube can measure angles with less noise than the method using an accelerometer. The two methods employed in this paper are found to be effective as a means of knowing various building characteristics.
