MECHANICS ANALYSIS OF FALL-DOWN PROCESS OF HIGH TUBULAR-TYPE BUILDINGS DEMOLISHED BY MEANS OF BLASTING

The fall down process of high tubular type buildings(chimney,tower etc) demolished by means of blasting is a complicated process of mechanics.Two kinds of mathematic models to analyse the mechanics in the fall down process are introduced by which some conclusions other than usual are obtained about the break possibility of buildings at their upper or middle parts when they fall down.Besides,precise mathematic expressions of some necessary parameters are given.
