摘要
本文以100m^3的玻璃钢球罐为例,根据旋转球壳无力矩平衡方程,计算出球壳的薄膜应力,从而确定了球罐各部位的厚度;按反应谱理论计算了地震作用于玻璃钢球罐的水平力;也计算了风载及支柱不均匀沉降而产生的附加压缩载荷;并对玻璃钢球罐的结构、制造及安装工艺等进行了设计,详细阐述了玻璃钢球罐设计的一般规律。
Taked 100 M^3 GRP globe tank as an illustration,based on force balance equation of no-moment of rotating globe shell,the globe shell's film stress is caculated and thus the thickness of every body of globe tank is determined in the paper. On the basis of the theory of the reaction manu- al,the horizontal force by which earthquake acts on GRP globe tank is worked out. Furthermore, wind force and extra press force produced by the unwell-distributed deposite of supposing columns are also discussed. In this paper, it makes designs about the structure,manufacture and installing process of GRP golbe tank and so on. Finally, the universal law on the design of GRP globe tnak is de- scribed.
