Field Measurement of Wind and Acceleration on Shanghai World Financial Center
摘要
Abstract
Based on the measured data of wind speeds and acceleration responses at the top of the Shanghai World Financial Center (SWFC) during the period from 2011 to 2016,the dynamic responses and dynamic properties were analyzed.The fundamental natural frequencies and damping ratios were identified by the envelope random decrement technique.The variations of dynamic responses with wind speed and the variations of dynamic properties with vibration amplitude were studied.The findings demonstrate that the standard deviation of acceleration increases in function of power along with wind speed,the fundamental natural frequencies decrease with the increases of vibration amplitude,while the fundamental natural frequencies decrease with the increases of vibration amplitude.关键词
