follow the opening shape formed by the concrete removal formation of the openings 33 creates a number of legs 35 that span the side between the two hinges 7 the height of the openings is sufficient so that an eccentric load is created and should extend beyond the elevation of the line 11 the dome 1 is also segmented or severed along the lines 39 using a wire saw or the like to form dome segments 41 preferably the cut goes through both the steel liner and the concrete outer shell but just the concrete could be severed if the steel liner cannot be cut explosives could be used to cut the steel liner in several predetermined places to facilitate dome segment separation this radial precutting permits the dome to stand safely while the overall dome is in its original position however the pre cut dome parts would come apart on explosion explosives could also be placed with the dome segments 41 to assist their separation then explosive charges are placed on the legs 35 to remove them the explosives can be placed by first drilling horizontal holes into or through the legs 35 and placing the explosives in the holes of course other shaped openings can be employed e g vertical or diagonal slots or through holes and the like the explosives are then detonated to remove the legs 35 once the legs 35 are blasted out an eccentric load is formed as shown in fig4 a and 4b whereby the dome 1 and remainder of wall 15 and wall 13 rotate or pivot about the reaction line and hinges 7 referring now to fig4 another option is.
