摘要
传统的水塔结构设计都忽略了水箱中水的晃动作用,把水当成质量块进行处理。将水箱中的水体当成一个TLD(调谐液体阻尼器),考虑水的晃动作用,根据有限元模拟分析,并结合实例对水塔结构进行抗震分析,得出水箱中的水有效地减小了水塔结构的地震反应,结构设计时应予以一定的考虑。
In the traditional water tower structure design,the slosh of water in the tank was ignored and the water was regarded as a mass block.In this paper,the water of the tank is took as a TLD(Tuned liquid damper) to consider the effect of the water sloshing.And then the seismic behavior of water tower was analyzed based on the finite element simulation analysis.The results show that the sloshing water of the tank reduces seismic response of water tower structures effectively.This useful effect should be considered when doing a structural design.
