【Abstract】 In this paper, several calculation & actual measurement methods on natural vibration period of buildings are introduced, and the applicability of different calculation methods is pointed out. As to the actual measurement methods, emphasis on pulsating wave analysis method, and it is compared to other two actual measurement methods on natural vibration period of buildings, and different actual measurement result from different method can be reasonably explained. At last, by comparing calculation & actual measurement result on buildings natural vibration period, it is found that empirical formulas can be used to calculate buildings natural vibration period, and the reduced calculation result is more reasonable.更多还原
