计入风重耦合效应高耸结构顺风向响应分析
Analysis of the downwind response of high-rise structures taking into account the wind-gravity coupling effect
摘要
Abstract
Wind⁃gravity coupling effect( WGCE) is a phenomenon that static and dynamic responses of high⁃rising structure acted by wind and gravity are changed. In order to study mechanism of WGCE, the method about nonlin⁃ear dynamic equation and equivalent linear random vibration theory is used to solve the problem. Calculated result indicates that gravity⁃rigidity ratio is an important parameter for WGCE. Natural frequency of structure decreases and response of structure increases with gravity⁃rigidity ratio of structure. Ground roughness,natural damping and average wind speed little impact on WGCE as value of gravity⁃rigidity ratio is small. While value of gravity⁃rigidity ratio is large, WGCE decreases with natural damping and average wind speed.关键词
