Comparative Analysis between Dynamic Simulation and Practical Result of Demolition of Building Structures by Blasting

Abstract:

Due to the complexity of blasting demolition of building structures, it is difficult to obtain an accurate enough approach for quantitative analysis that can be applied to the constructional engineering. In this paper, dynamic simulation of the demolition blasting process is conducted with the finite element software ANSYS/LS-DYNA. By comparing the dynamic simulation with the practical result, it is found that the calculated results are very close to the practical collapse process. It is further proved that dynamic simulation can be conducted for the quantitative analysis of the collapse process.
