摘要

烟囱倒塌的过程中可能会在某处断裂.本文研究了质量非均匀的烟囱倾倒过程中各部位的受力与扭矩,并通过扭矩极大值点找出烟囱断裂位置.

Abstract

It is generally known that chimney might break at a certain place before it hit the ground during a demolition blasting. However,previous models have assumed that the mass distribution of the chimney is uniform. The chimney model analyzed in this paper is a more realistic one with non-uniform mass distribution.By seeking the maximum point of the torque,the possible rupture point of the chimney is given.
