An Experimental Study on Confined Steel Structure Blasting Demolition
The Demolition blasting has been applied for buildings and structures so far.In this study, however, a confined vessel blasting filled with water has been focused.A small amount of explosives were placed in a sealed vessel with water, perfect elastic body, supposed as a relay agent in it, and the blasting aspect was observed.Blasting pressure was standardized by Abel s equation of state.In result, if there was a relay agent in it, the pressure vessel was torn apart with smaller power than its tensile strength.If there was not, it needed 7.1 ~ 8.5 times as much power as the previous one, and the blasting pressure had not also affected the demolition and it had gone or vanished until it reached a certain point, In terms of pressure vessel made by steel, the plastic failure was took a place, and the first yield point happened along the welded area as a form of heating plastic failure we thought.
