| 摘 要： | 介绍了一复杂群塔结构节段刚性测压试验概况和主要试验结果,讨论了结构典型部位风压分布的基本特征和结构风压分布的基本规律.试验结果表明,由于该结构由多个单体高耸塔结构组成,相互干扰严重,风压的分布相当复杂.根据风压试验结果得到了风力沿各塔高度的分布,并讨论了分布规律,进一步得出基底剪力系数和基底弯矩系数,分析了最危险风向,给出了用于结构设计的荷载建议.

| Abstract: | This paper presents a wind tunnel test on section models of a complex group towers system and the wind pressure distributions on the complex towers.Primary characteristics and rules of wind pressure distributions on representative positions are described.The results obtained from the experiment apparently show that the pressure distributions are very complicated due to the serious interference among the multi-high-rising towers.The wind force distribution along the height of towers is also discussed.Further... |
