摘要

将球壳和上支柱处理为刚体,球罐质量集中于球心,下支柱处理为结构梁,拉杆处理为只能受拉的绳索(计算中只考虑受拉拉杆),按结构力学分析计算球罐水平刚度和自振周期,以及在水平地震力和风力载荷作用下,下支柱和拉杆的应力(也可考虑基础不均匀沉降球罐整体倾斜的影响)。通过研究得到的计算方法可用于球罐的工程设计和计算。
In this paper we tread tank sheel and upper tie-rod as rigid bodies,and the mass of tank concentrates on the center of sphere;tread the lower support column as a structural beam and tread tie-rod as a rope that can only bear tension(in calculation,only consider tension bearing tie-rod).And then,by using structural mechanics,we analyze and calculate tank horizontal stiffness and natural period of vibration,and stress of lower support columns and tie-rod under the effects of horizontal seismic force and wind force(may also consider th effects of the whole tank inclination caused by the nonuniformly sinkage of foundation).The calculation method gotten from this study may be used in engineering design and calculation.
