摘要
结合某通风除尘钢烟囱,分析了有无开洞的钢烟囱的动力特性及钢烟囱的横风向风振问题。研究结果表明,开洞钢烟囱受力性能不利,更易发生横风向的共振。
In combination with a ventilation dedusting steel stack, the dynamic characteristics and cross wind-induced vibration problems of steel stacks with or with- out holes were analyzed. The results show that the mechanical behavior of the holed steed stack is unfavorable, and it is more likely to occur across wind resonance.
