Abstract :
The separate element and common node model is setup to simulate reinforced concrete material at first, which could take fully account of the intensity difference of concrete and rebar. And then a 16-storied frame structure is build with this kind of model. The blasting demolition process of the structure is simulated. The mechanism of collapse process and failure of column are analyzed. Finally, the scopes of collapse of calculation and practice are compared, and the errors of forwards and backwards distance are +11.9 and -16.6%. The simulation result has great practical significance to determine blasting parameters and optimize design.
