文档介绍：人体对高层建筑风振的舒适度研究摘要高层建筑风荷载引起的效应在总荷载效应中占有相当大的比重,甚至起决定性作用,因而风荷载及风荷载作用下结构的静、动力响应常常是高层结构研究的主要内容。振动舒适度问题是现代工程结构普遍存在的问题,也是工程结构可靠度研究的一个主要内容。舒适度分析主要针对风荷载而言,尽管判断舒适度的标准有多种,但目前采用最多的是建筑的最大加速度。这一课题是伴随超高层结构出现的,因而对其进行的研究还不够深入。尽管各国对舒适度验算提出了一些计算方法,但其合理性是值得探讨的。目前我国的《高层建筑混凝土结构技术规程》(JGJ3-2002)和《高层民用建筑钢结构技术规程》(JGJ99—98)规定舒适度的验算是通过计算结构顶点加速度值来衡量的。本文研究的重点是人体对高层建筑结构风振的舒适度,主要的研究内容如下:,确定振动舒适度的量化指标,建立高层建筑风振烦恼率公式。 ,对高层建筑风振舒适度验算方法存在的几个问题进行分析,完善我国规程的风振舒适度评价标准:(1)分析了不同振型形态下风振舒适度的差异;(2)分析了因人员空间分布差异引起的舒适度差异;(3)对基础隔震建筑的风振舒适度进行了研究。 ,使用SAP2000对二十层的一栋高层建筑进行时程分析,得到其顶点加速度时程,基于烦恼率模型对其进行风振舒适度分析。同时对基础隔震建筑进行了风振时程分析,研究了基础隔震措施对风振舒适度的影响。关键词:高层建筑;烦恼率;舒适度;加速度硕士学位论文 Abstract The wind—induced loadeffect takes agreat proportion intotal load effects and even plays adecisive ,the structural static and dynamic response under wind loads are usually the main content of is one mon problems in current engineering structure and amain content of structure reliability reliability analysis ismainly aimed at the wind—induced spite ofvarious standards fort j udgment,the maximum acceleration ofthebuilding monly used injudgment.
