キーエレメント指標を用いたS造建築物の発破解体計画 -層数が異なる場合の比較-
Abstract
日本では,高度経済成長期に建設された建物の耐用年数が近づいていることから,それら建物の解体の需要は今後高まると予想される.このような建物の解体方法として,一般的にはクレーンなどの重機が用いられるが,解体対象となる建物が大規模になるにつれ,解体工期の長期化によるコストの増大や,作業員のリスクが懸念される.
In this paper, a blast demolition planning of buildings based upon key element index in which the contribution of a column to the strength of the building can be investigated numerically, is described. The purpose of this study is to develop a blast demolition planning tool that can even demolish complicated buildings. The relationships between integrated key element index value for the removed columns and the sum of heights of remains after the demolition and the number of blasted columns are investigated. We also applied the numerical code to investigate the demolition behaviors and compared the results with the models of different layer numbers.
