Since the mid-1980s, approximately 4,160,000 apartments have been built in Korea, and more than 70 % of these apartments were high rise apartments having 11 floors or more. Meanwhile, most of the apartments were built in the wall-slab structure, and this kind of wall-slab high rise apartment is a building structure native to Korea of which its demolition cases cannot be found in other countries. Consequently, it can be said that it is absolutely necessary to develop and establish a safe and effective demolition technology in order to prepare for the upcoming time for demolition of wall-slab high rise apartments. The purpose of this manuscript is to introduce cases where the explosive demolition method has been applied on ferroconcrete buildings compounded of the RC structure and the wall-slab structure.
