Ground loading from BLEVE through small scale experiments: Experiments and results

The ground force generated by a BLEVE is hazard that has been seldom studied, even though source of many research works in the past decades. However, emergency responders have asking questions risk and consequences on bridge other critical infrastructures for while, with no answer so far. Moreover, tank truck accident Bologna August 2018 shown collapse may result from such scenario. This paper presents experimental work done small scale apparatus reproducing realistic failure cylindrical tube. Load cells were placed under base plate holding tube to measure local explosion. Forces 10 kN 55 measured 50 mm diameter 300 length failing at pressures 32 Bar. signals are interpreted together imaging internal pressure signal. synchronization between violent boiling, repressurization vessel strong clear through this comparison. Different observed depending fill level weakened maximum impulse vary almost linearly liquid level. It less influence weakened/opening More data required conclude parameter influence.
