结构的鞭梢效应分析
Analysis of Whiplash Effect of Structures
摘要
Abstract
It is explained why the whiplash effect occurs to building having prominent part on its top by analysis of building of multiple degrees of freedom on earthquake effect. It is shown that whiplash effect can occur when the fundamental frequency of prominent part equals to the natural frequency of the monolithic structure containing main part and prominent part, or this frequency nearly equals to the earthquake frequency. This is proved to be right by example. Decreasing the influence of whiplash effect, people shouldn't only increase the stiffness of prominent parts while adjusting structure's stiffness and mass distribution by dynamic computation in order to make frequency difference of prominent part and the monolithic structure bigger. Thus, more reliable data could be supplied for design of structures.关键词
