[提要]  本文研究了彎曲型高層結(jié)構(gòu)自振頻率方程的特點(diǎn)，提出了自振頻率的迭代解法。該法克服了圖解試算法步驟繁瑣不夠準(zhǔn)確的缺點(diǎn)，能夠迅速地算出精確結(jié)果。
[關(guān)鍵詞]  彎曲變形 高層結(jié)構(gòu) 豎直懸壁梁  自振頻率 迭代解法

In this paper, the characteristics of natural frequency aquation of bending mould high-rise structures are studied, the iterative solution of natural frequeney is presented. This method overcomes the defect of the trial calculation mathod of graphic analysis,that its steps is overelaborate and reult is incorrect. And the exact result can be get quickly using the iterative solution.
Keywords: bending deformation; high-rise structures; vertical cantilever beam; natural frequency; iterative solution
