通过工程实例,用雅可比法分析了悬挂环形钢水箱的烟囱自振特性、指出不宜直接采用规范的计算简化式计算烟囱基本周期和振型向量,并提出应该采取的构造措施,可供类似工程参考。
By engineering example, the Jacobi method was used to analyze the natural vibration characteristics of the chimney suspended by the annular steel tank. It was pointed out that it is not advisable to calculate the chimney fundamental period and mode shape vector directly using the standard simplified calculation formula and to propose the structural measures that should be taken for similar projects reference.
