The Failure Behaviour of Reinforced Concrete Panels Under Far-field and Near-field Blast Effects

Abstract

The distribution and intensity of blast pressure from far-field and near-field blasts can produce remarkably different patterns of loading on a reinforced concrete (RC) panel and can cause the panel to experience different modes of failure. Behaviour of RC panels, designed without consideration for extreme loading was investigated to analyse their damage and failure modes under different blast scenarios. The damage and failure modes of RC panels tested in two different full scale open air blast trials are presented. One of the tests was conducted in far-field condition with 40 m standoff distance. The other test was conducted on panels in near-field condition with standoff distances up to 2 ..
