摘要
结合具体工程实例,利用有限元软件ANSYS,对塔架式钢烟囱结构整体动力特性与只考虑塔架和只考虑烟囱与楼板相互作用两种情况进行对比研究,研究结果表明:整体计算模型能真实地反映塔架、烟囱与楼板之间的相互协调、互相制约的作用,较好的反映了塔架式钢烟囱结构的真实动力特性;建议在设计中考虑烟囱、塔架与楼板的相互作用。
Combining with specific project example,using finite element software ANSYS,the paper made comparison research on the whole dynamic characteristics of tower steel chimney structure and considered only the tower and considered only the interaction of chimney and floor two kinds situation,research shows that the whole calculation model could really reflect the coordination and interaction relationship of tower,chimney and floor,better reflected the real dynamic characteristics of tower steel chimney,considering the interaction of chimney,floor and tower in design.
