摘　　要：结合工程实例,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GB50051-2002《烟囱设计规范》的计算简化式计算烟囱基本周期和振型向量,并提出应采取的构造措施,可供类似工程参考。According to Jacobian matrix,natural vibration characteristics of chimney and suspended annular molten steel tank are analyzed,and the engineering example is also given.The proposed formulas of fundamental periods and vibration modal of the chimney in Code for Design of Chimney(GB 50051-2002) are improper.The details are suggested based on the engineering.

关 键 词：烟囱 钢水箱 自振特性 地震作用
