Analysis on Drop Tower Subjected to Explosion Superpressure and Static Loading

摘要

TNT explosion superpressure effect on steel reinforced concrete drop tower is calculated by semi-infinite space explosion similarity law method. And drop tower subjected to static loading is simulated by finite element software ABAQUS. The results indicate that superpressure effect on drop tower is insignificant for thirty kilogram TNT. The stress distribution of drop tower under certain loading is gained. It shows that the maximum Mises stress is about 5.9MPa, the maximum tension stress is about 4.3MPa and the maximum compression stress is about 4.6MPa. And wind and snow pressure effect on drop tower is discussed. The results show that natural influencing factors should be considered in drop tower structure design.
