Title: Numerical Simulation for Explosion Load in Underpass Structure
Abstract: In order to master the properties of blast shock wave on buildings in the explosion disaster,a numerical model for calculating the blast overpressure in the underpass was established by using explicit dynamic nonlinear finite element software LS-DYNA;the influence of the grid division on the calculation result of the blast overpressure loading was analyzed;the regularities of blast overpressure loading to the target building under different TNT equivalent and distance were obtained.Based on the numerical results,some principles in the explosion disaster prewarning,design and reinforcement of a blast-resistant building can be applied in the actual projects.
