Abstract
One of the objectives of this study is to perform some blast demolition analyses of framed structures using a dynamic finite element code, whose validity against impact collapse problems of full-model large-scale structures has recently been developed and verified. Another objective of this study is to develop a mimic demolition experimental system that uses magnetic devices to express member fracture caused by explosion. The magnetic field of the devices is controlled by a blast interval controller and power switches, which control the binding of each connection in the framed structure. The experimental system does not use explosives or any such dangerous substances, and multicycle use is possible. Some experiments are carried out for comparison with the numerical results.
