摘要 以某选煤厂浓缩池网架屋盖为背景,通过有限元软件进行建模分析,探究杆件腐蚀损伤程度和结构的初始缺陷对网架结构的整体稳定性能的影响。结果表明,该网架结构杆件的腐蚀降低了结构整体稳定性;而初始几何缺陷对该结构的整体稳定性影响较小,该结构属于缺陷不敏感结构。 based on the grid roof of the concentration pool in the coal preparation plant,the influence of the corrosion of members and the initial imperfection of the structure on the overall stability performance of the grid structure is studied through the finite element analysis software.The research results show that the corrosion of the members in the grid structure reduces the overall stability of the structure,the initial geometric imperfections have no obvious influence on structural overall stability,so the structure is insensitive to the initial imperfection.
