基于能量的结构风振控制设计方法研究
|
摘要
建立结构任意高度单位风能量计算公式、各楼层总输入风能量计算公式、结构总输入风能量计算公式。在主体结构弹性状态下,给出了粘滞和粘弹性阻尼器的能量耗散公式及结构总能量输出公式,提出基于能量的结构风振控制的设计流程。以某高层建筑结构为例,验证所提基于能量的结构风振控制方法可有效实现结构风振控制设计,达到有效抑制结构风振反应的目的。
Formulas of unit wind energy at any height,wind input energy of each story and total input energy of a structure were deduced and proposed according to energy balance principle here.All the input energy was assumed to be dissipated by dampers,such as,viscous and viscoelastic dampers.The total output energy was then calculated according to dissipation energy of all dampers in elastic condition.The structural design flow-chat of energy-based wind vibration control was therefore presented in the light of relationship between the input energy and output energy.A high-rise building was adopted as an example to verify the feasibility and rationality of the proposed energy-based design method.The results showed that the proposed method can be used reasonably as a wind-resistant design method of controlled buildings and better control effects can be achieved.
