In order to utilize for seismic investigation of existing building, the characteristics of 1 st natural period T_1 were investigated, and following facts were understood. 1)T_1 measured by vibration test, earthquake observation and others with each level of slight, minor, and large amplitude, these average characteristics were analyzed. Regression analysis was applied using the building height H and T_1, and the analyzed formula was compared with experimental formula of design. 2)The cause of the growth of T_1 is that the effects of secondary component of building, and otherwise. T_1 is extended by structural earthquake damage and superannuation. If the T_1 in case of earthquake exceeds the twice of slight amplitude level, it can be said dangerous. 3)When remarkabledifference has T_1 of building to average value, detailed analysis is needed.
