Abstract: By using the finite element method and multi-rigid-body dynamics numerical simulation method,simulation analysis of demolition blasting of frame structure building is carried out.This technology can predict and reproduce the processes of destabilization,disintegration,and collapse and the problem of accumulation zone scope,which can improve the safety and reliability of the demolition blasting scheme.

Key words: frame structure building, demolition blasting, numerical simulation, method of finite element, multi-rigid-body dynamics
