摘要(Abstract):
本文分析了烟囱倾倒运动规律和倾倒过程的内力分布,给出了任一时刻烟囱内力分布的计算公式。由具体实例计算可知,烟囱在倾倒过程中的破坏是由拉应力而不是剪应力造成的。文章还对烟囱的后坐和前冲进行了分析。
In this paper,the motion regularity and intemal foras distribution of chimney when it is toppling are analysed. The formulas for calculating the intemal forces distribution are presented. A calculation example showed that it is pulling stress but not shearing stress to cause the chimney broken during toppling.
