On the demolition works of steel buildings which reach their durable period, the blasting demolition method might be very effective. In order to control the demolition of steel buildings safely and surely, it is necessary that the minimum amount of high explosives can be estimated. Therefore, as the basic study which probes the impact fracture mechanisms of steel plates with shaped charges, we prepared the shaped charges, whose design parameters are materials of liners and amount of high explosive, and obtained the control of notch depth of steel plates through many experiments. And we carried out the Metallurgical analysis for grasping dynamic effects on steel plates against impact force.
