After a severe earthquake, it is necessary to immediately judge the safety of school buildings which serve as evacuation shelters. Focusing on school buildings with short columns, the column likely to fail first is determined from seismic evaluation data. A monitoring device is installed which sends warning signals when the column width enlargement exceeds a predetermined threshold. Two prototypes, detailed and simple, were evaluated through experiments. The detailed device can precisely measure deformation although it is expensive and requires more maintenance. The simple device is cheap and easy to install although a small error is introduced in the measurement.
