【摘要】 本文详细研究了带有多自由度突出物的结构产生鞭梢效应的原因,指出当突出物的基本自振频率与整体结构(包括主体结构与突出物)的固有频率相同,且又与地面运动扰频相接近时,最易发生鞭梢效应。更多还原

【Abstract】 In this paper,based on both aspects of free vibration and earthquake effect analysis of building,it isexplained why the whiplash effect occurs to building having prominent parts of multiple degrees of freedomon its top.It is shown that the whiplash effect can occur if the fundamental frequency of prominent parts e-quals to a natural frequency of the entire structure containing main parts and prominent parts,and this fre-quency should nearly equal to the earthquake frequencies.更多还原
