Abstract
In this paper, we present the result of an analytical investigation concerning the demolition range for the pre-weakening of load-bearing wall in explosive demolition. Pre-weakening of load-bearing wall is usually conducted based on field experience because reliable specifications or guidelines for the design of pre-weakening have not yet been established in Korea. This study is one of the efforts to develop such a reliable specification or guideline for the pre-weakening process. Hence, the focus of the study is on the estimation of pre-weakening range of load-bearing wall. For the purpose, a finite element analysis (FE analysis) was conducted, and a pre-weakening range of load-bearing wall was suggested based on the analysis result.
