建立了某高压输电塔结构的梁—杆混合空间模型，应用ANSYS软件进行了该高压输电塔结构梁—杆混合空间模型的模态分析，利用子空间迭代法计算了该模型的前10阶自振周期、频率及振型，结果表明高压输电塔结构的梁—杆混合空间模型更接近于结构的实际受力状态，计算所得结构基本自振周期与现行建筑结构荷载规范经验公式及电力部门经验公式吻合较好。
建立瞭某高壓輸電塔結構的樑—桿混閤空間模型，應用ANSYS軟件進行瞭該高壓輸電塔結構樑—桿混閤空間模型的模態分析，利用子空間迭代法計算瞭該模型的前10階自振週期、頻率及振型，結果錶明高壓輸電塔結構的樑—桿混閤空間模型更接近于結構的實際受力狀態，計算所得結構基本自振週期與現行建築結構荷載規範經驗公式及電力部門經驗公式吻閤較好。

The paper establishes the beam-rod mixed space model of some high-voltage transmission tower structure,adopts ANSYS software to undertake the model analysis of the beam-rod mixed space model of the high-voltage transmission tower structure,applies the subspace iteration method to calculate the former 10 model self-vibration period,frequency and vibration type of the model,and proves by the result that the high-voltage transmission tower structure’s beam-rod mixed space model is close to the factual stressed status of the structure,and the calculated structural basic self-vibration period is consistent with the loading experience formula of current architectural structures and power departments.
