| Abstract
|
Natural vibration period is an important parameter for high-rise building, Based on 414 high-rise buildings completed or passed over-limit approval in China, the distribution law of natural vibration periods is analyzied. In order to satisfy the design requirements, such as global stability, story drift limit and minimum shear-gravity ratio, the reference ranges of fundamental periods T1 are 0.3 ~0.4 when the structural heights H >= 250 m, when 150 m <= H < 250m, T1=0.25 ~0.4 , when 100 m <= H < 150 m, T1 = 0.2 ~0.35 , when 50 m <= H < 100m, T1 = 0.15 ~0.3 . These can provide reference data for controlling mass and rigidity of high-rise buildings. |
