| Summary: | Concrete elements under high-speed projectiles effect has an increasing interest
recently. Understanding to what extent the concrete can resists the effect of
projectiles, very necessary in design structures in order to save the occupants.
The objective of this study is to develop improved numerical model for
predicting dynamic response of RC slabs under HSP attack. The present study
presents a total of 12 concrete slabs casted and tested under plain and steel
reinforcement. Parameters investigated were slab thickness, (50 mm, 100 mm,
and 150 mm) and projectile type. Dynamic simulation was performed also and
the results obtained have been discussed and compared with experimental
response. Generally, it was concluded that penetration depth was controlled by
target thickness regardless the steel reinforcement. Good alignment achieved
between numerical and experimental date with respect to penetration depth and
crater vale.
