BLAST TESTING AND SIMULATION METHODS

Popis výsledku v původním jazyce

Some analysis results from the experimental investigations about the behavior of concrete hardened structures and fiber reinforced panels subjected to explosions presented. In this part some field tests conducted in cooperation between University of Defence, Czech Technical University and Czech Army Corps of Engineers on High Performance Fibre Reinforced Concrete (HPFRC) slabs against blast wave caused by explosion of charge according to STANAG 2280 presented. There were tested several configurations of charges and slabs within distances ranging from 1 to 5 meters. Simulations in AUTODYN software were conducted to compare crack and damage development of mathematical models with tested slabs. It’s also describes the use of ultrasonic testing methods for examining slabs made from cement based materials. For the detection of cracks, in full-scale slabs before and after the explosion, ultrasonic pulse method was used. Its some new study aimed on protection of civilian infrastructure against explosion loading due the natural and accidental hazards that has been receiving more attention in recent years such as a gas detonations, terrorist attacks, etc. Occasional engineering explosion accidents during the mining activities is of the great attention of the researches from the reason of the local city safety during operational accidents of the mining character, including safety of underground premises. Full-scale experiment has been conducted to analyze pressure effects during ignition of methane-air mixtures in the interior vented explosion within a selected object. The confined explosion causes more damage than the damage caused by a similar external explosion. So that’s very important to understand not only characteristics of an interior explosion due to methane-air mixture explosion, but specially, structural analysis of response of the real structures for prediction of their collapse.
