DISCUSSION ON "DEVELOPMENT OF ANALYTICAL AND EXPERIMENTAL SYSTEMS FOR BLAST DEMOLITION OF FRAMED STRUCTURES" (Daigoro ISOBE, Masashi EGUCHI, Kensuke IMANISHI and Zion SASAKI, J. Struct. Constr. Eng., AIJ, No. 612, 73-78, Feb., 2007)

Abstract

The above mentioned paper deals with the blast demolition of structures, which has been practical technique for four decades. Electromagnetic holders were used in the demolition experiment. The discusser wants to ask whether electromagnetic holders can simulate the actual break phenomena of reinforced concrete members due to explosion or not. There is no data on the actual behaviors of blast demolition in the paper. What is the strongest argument about the practicality of the analytical and experimental methods developed by the authors of the paper?
