Zusammenfassung:In this paper, a method to evaluate the roof snow load using acceleration measurement is proposed. Its applicability was confirmed by being applied to snow load on a semi-full-scale wooden structure building model. The natural frequency change caused by the roof load variations was investigated by acceleration measurement using an inexpensive instrument. By the comparison of the measured result to the actual snow load measured by load cells, it was shown that it is possible to estimate the snow load on the roof within an error of 20% at maximum even with the inexpensive accelerometer.
