【摘要】 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。更多还原

【Abstract】 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 highvoltage 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.更多还原
