本文用弹性基础梁理论导出各向异性玻璃钢卧式贮罐中加强圈有效宽度,用差分法解决了径向挠度计算问题。并对50M~3贮罐进行了试验研究,测试结果与理论计算较一致。 In this paper, the effective beam width of the anisotropic FRP horizontal tank is derived from the elastic foundation beam theory, and the radial deflection calculation problem is solved by the difference method. The 50M~3 storage tanks were tested and the test results were in accordance with the theoretical calculations.
