摘要:
强风作用下某结构高耸的通信塔可能发生倾覆的问题,根据惯性风荷栽法理论,采用数值风洞得到的塔体表面沿高度分段风压体型系数,考虑塔体前6阶振型的影响,得到强风作用下13个风向塔体风振响应计算结果基于塔体风振响应结果,并考虑一体化机房上作用风力,对此通信塔进行抗倾覆研究通过分析研究,得到了此通信塔抗倾覆最不利风向角为90°,移动基础安全设计重量为15.8t分析结果表明,计算方法可靠合理,同时也为通信塔类结构的风振和抗倾覆分析提供一种可参考的方法.
Abstract:
A telecommunication tower is liable to be overturned under strong wind since the tower body is ahigh-rise structure. Based on inertial wind load method, in consideration of the distribution of multiple spatial6 models and the segment shape coeficients of tower body according numerical wind tunnel, wind-induced re.sponse of tower body in 13 different wind attack angles are calculated, Based on the wind-induced responseand the wind loads on motor room, analysis of anti-overturning of tower is checked. The research results arethe most unfavorable attack angle is 90°direction and the scientific data for the design of mobile foundation is15.8t. The results of analysis show that the method adopted in this paper is reasonable, at the same time themethod is presented for the analysis of wind-induced and anti-overturning of structures such as the telecommu.nication tower.
