The Research of Wind-induced Control based on the energy balance principle

Abstract

随着建筑功能的多样化,以及新材料、新结构与新体系的迅猛发展与应用,高层建筑的楼层数逐渐增多,高度也逐渐增高,结构也变得越来越柔,这给我们的结构设计带来了新的要求和挑战,结构的抗风设计也因此变的更加重要。传统的抗风设计方法已不能很好的满足设计的要求,即使满足了要求,也是不经济的。有效、可靠、安全、经济的方法是采用结构的风振控制技术,即通过在结构中设置减震装置来减小结构的动力响应。本文在以往研究的基础上,基于能量的平衡原理,分别对一维和三维建筑结构进行风振控制研究,主要完成了以下工作: 1、建立76层Benchmark模型的阻尼器控制系统的动力学方程,基于能量的平衡原理,利用遗传算法对阻尼器的位...With the rapid development and application of multi-functional buildings, as well as new materials, new structures and new systems, the global witness the rise of constructing high-rise buildings, the competition of the highest building in the world is very keen, the record is refreshed continuously. Consequently, the structure is subjected to increasing wind load with comparatively flexible bendi...学位:工学硕士院系专业:建筑与土木工程学院_结构工程学号:2532010115171
