［摘要］為了完善結(jié)構(gòu)基本自振周期的估算公式，填補(bǔ)我國(guó)高層及超高層建筑基本自振周期估算公式空白,收集了我國(guó)近年來(lái)的302棟已建和在建的高層及超高層建筑的相關(guān)數(shù)據(jù)。通過(guò)MATLAB編程對(duì)其進(jìn)行擬合，得到了我國(guó)高層及超高層建筑基本自振周期的估算公式。并且利用收集到的建筑相關(guān)數(shù)據(jù)，分別與美國(guó)、歐洲、日本規(guī)范以及我國(guó)《建筑結(jié)構(gòu)荷載規(guī)范》（GB 50009—2012）中規(guī)定的估算公式的計(jì)算結(jié)果進(jìn)行對(duì)比分析。結(jié)果表明，所提出的結(jié)構(gòu)基本自振周期估算公式更為準(zhǔn)確。最后，重點(diǎn)討論了高層及超高層建筑設(shè)計(jì)中適宜結(jié)構(gòu)基本自振周期的選取。

Abstract: In order to improve the practicability of estimation formula for the fundamental natural period of high-rise and super high-rise buildings, a new estimation formula for fundamental natural period has been established by MATLAB data of 302 constructed and under-construction  high-rise buildings. Besides, the new formula was compared with the estimation formula from United States, Europe, Japan and Load code for the design of building structures（GB 50009—2012）. The results show that the new estimation formula for the fundamental period of high-rise  and super high-rise buildings is more accurate and reasonable. At last, the appropriate fundamental natural period for high-rise and super high-rise buildings was discussed.

Keywords: high-rise and super high-rise building; fundamental natural period; estimation formula; shear-gravity ratio; comfortableness
