【摘要】 针对地势高差与档距对输电塔线体系平面外自振频率的影响,在有地势高差的情况下改变不同档距,利用SAP2000有限元分析软件建模,对塔-线耦合体系平面外自振频率进行分析计算,获得了有地势高差情况下不同档距的塔-线耦合体系平面外自振频率规律,对输电塔抗风、抗震设计具有参考价值。更多还原

【Abstract】 Aiming at the influence of topography elevation difference and span on natural frequency of vibration for outside plane of transmission tower-line system,SAP2000 finite element analysis software is used to calculate the natural frequency of vibration for outside plane of transmission tower-line system by changing different span at the condition of topography elevation difference.The obtained natural frequency of vibration for outside plane of transmission tower-line system has reference for wind and seismic resistant design of transmission tower.更多还原
