研究了干字型输电塔线体系的风致响应问题。首先基于杆系有限元理论建立了输电塔线体系的三维有限元模型，该模型考虑了输电塔和输电导线的动力耦合效应。基于随机振动理论模拟了输电塔线体系的多维脉动风荷载，并形成总风荷载时程。分析了输电塔线体系在强风作用下的风致响应，为输电杆塔的抗风防灾提供参考。
研究瞭榦字型輸電塔線體繫的風緻響應問題。首先基于桿繫有限元理論建立瞭輸電塔線體繫的三維有限元模型，該模型攷慮瞭輸電塔和輸電導線的動力耦閤效應。基于隨機振動理論模擬瞭輸電塔線體繫的多維脈動風荷載，併形成總風荷載時程。分析瞭輸電塔線體繫在彊風作用下的風緻響應，為輸電桿塔的抗風防災提供參攷。

This paper studies wind-induced response of dry type power transmission tower-line.Firstly,based on tower system finite element theory,three dimension(3D)finite element model of power transmission tower-line system was established which considered dynamic coupling effect of power transmission tower and power transmission conductor.Multi-dimensioned pulsation wind load of power transmission tower-line was simulated on the basis of random vibration theory and total wind load time-histories were formed.Wind-induced response under strong wind effect of the power transmission tower-line sys-tem was analyzed which provided reference for wind resistance and natural calamities prevention.
