Study on Damage Characteristics of Reinforced Concrete Structure for Internal Explosion
In order to reveal the damage characteristics of internal explosion, the internal explosion of closed RC structure under incremental charges manner until structural damage are simulated by LS-DYNA code. The weight changes of charge influence on structure damage and distribution law of characteristic parameter of shockwave on the typical position are also discussed in this paper. The results show that, the distribution of shockwave overpressure on the walls under different weight of charge obey three kinds of linear laws as following: affected by one wall, two walls and three walls, respectively. The distributions of impulse on the walls under different weight of charge obey their distribution curve respectively when the structure is undestroyed, but the impulse will deviate from the distribution curve when the structure is destroyed. And the damage situation of RC structure under internal explosion is graded.
