Abstract

This paper only deals with the effect of hard missile impact (impacting missile
is so stiff that its deformability is negligible to the target deformability) and missile
velocity between 28 to 103m/s are considered. Available formulae for prediction
the scabbing and perforation thickness of concrete structure impacted by solid
missile are summarized and reviewed. Based on statistical analysis of existing data,
two new more safe formulae have been proposed for predicting the scabbing and
perforation thickness of concrete structures due to impact by solid missiles. The
new scabbing and perforation thickness formulae include, missile parameter which
are weight of the missile(W), diameter of the missile(D), velocity of the missile
(V), and target parameter which are concrete member thickness (t), and concrete
member strength (fc'). The simplified formulae for scabbing and perforation
thickness of concrete structure impacted by solid missile are presented in terms of
penetration depth (Xp). Comparison between present scabbing and perforation
thickness of concrete structures impacted by solid missile with other research
results are presented.
