Abstract: By using the ANSYS/LS-DYNA finite elements software, the numerical simulation research is conducted to the reinforced concrete structure directional collapse using integral model. Based on the calculation results, this article analyzes the reinforced concrete structure collapsed in the process of forward, back, bloating, and makes a quantitative description to the entire collapse process. Compared to the Heibaishui hotel collapse process by blasting project, it shows that integral model simulation results can agree well with the actual and also has guiding significance to the actual project.
