【摘要】 本文根据随机振动的基本理论,推导了在阵风作用下适用于架空导线、铁塔及其它类似的线状高耸结构的风振计算通式,并对导线及铁塔风振系数的一般规律作了分析,与全尺寸实测资料、现行的规程及(IEC)国际标准作比较,结果说明,所推荐的理论计算值与实际比较接近,而现行规程的规定值则偏低。更多还原

【Abstract】 Based on the basic random vibration Process,this paper gives the derivation ofthe general calculation formula adaptable to the conductors and steel towers of over-head line and similar highrise structures under the action of gusty wind and the ana-lysis of the general pattern of aeolian vibration coefficients of conductors and steeltowers.It also gives the comparison with the data of full-scale tests and current regu-lations as well as the International IEC standards,the results show that the recommen-ded theoretical values are more conform with the actual values,but the values speci-fied in the current regulations are comparatively a little bit low.更多还原
