Computer Simulation Of The Collapsing Course Of Frame Construction By Blasting

In view of some problems that occur at controlling blasting demolition of reinforced frame structures, this paper summarizes the application and study of blasting demolition of buildings at present, and studied the course of lose stability and collapse occurring during blasting demolition of reinforced frame structures through theory analysis, numerical simulation.This paper discussed the collapse patterns of reinforced frame structures and its mechanism first, and then analyzed the movement stability of construction applying the theory of controlling blasting and dynamic; After that the lose-stability condition of reinforced frame structures during blasting demolition was studied, a mechanical model of blasting demolition of reinforced frame structure was established; At last this paper applied ABAQUS analysis software to reinforced frame structures taking lose-stability as the initial condition.Applied the achievements to the simulation the course of collapse during the blasting demolition of Wuhan Outbeach garden and Wuhan Emporium, the result of the simulation matches the real engineering condition well. Though that it can be figured out that the collapse course during blasting demolition of to reinforced frame structures can be well simulated using the achievement, the simulation results of this paper can play a good guidance role on theoretical research and design about controlling blasting of reinforced frame structures.
