Abstract:
With the development of offense and defense strategy in future war and the application of high tech weapon, the demand is much improved to the resistibility level of defense engineering. LS-DYNA3D software is adopted to simulate the situation causing by the explosion of the commonly short concrete column and Short Concrete Column with Steel tube confined. The comparison includes chamber causing by explosion and nodes' displacement. The results show that steel tube-confined concrete structure can confine the displacement of core concrete, improve the structure's capacity of resisting explosion effectively, and enhance structure's elasticity and firmness.
