スパン数の異なる建物におけるキーエレメント指標の分散を用いた発破解体計画
Abstract
本稿では,スパン数の異なる複数の10層の建物に対し, KI
In this paper, a blast demolition planning of buildings using variance of key element index, in which the contribution of a column to the strength of the buildings can be numerically evaluated, is described. The purpose of this research is to seek a blast demolition planning scheme that improves the efficiency of demolition and considers safety during demolition. By conducting collapse analyses using the ASI-Gauss code and by observing the scattered distance after the demolition, the relationship between the number of removed columns for blast demolition and the height of remains after the demolition, the safety and the efficiency of blast demolition of buildings using variance of key element index is investigated. We compared the results between the buildings of different span numbers.
