Abstract
A case study in the IRIS_2010 benchmark exercise in the
OECD/NEA/CSNI/IAGE framework covered a reinforced
concrete wall subjected to impact by a hard steel missile
with a mass of 47 kg and an impact velocity of 135 m/s.
The considered simply supported square slab was 2 m wide
and 25 cm thick. The expected and realized collapse mode
was perforation. Tests were carried out with a VTT impact
test facility. A VTT team also participated in the blind
benchmark exercise. Analyses were carried out using a
one-dimensional penetration/perforation model and the
Abaqus/Explicit Finite Element (FE) program. Selected
calculation results were presented at the IRIS_2010
Workshop. Based on Workshop presentations and discussions
it was concluded that the nonlinear analysis of
reinforced concrete structures is a challenging task and
calculation results are quite sensitive, e.g., to
material parameters and modeling assumptions. Various
sensitivity studies of this so-called punching test were
carried out afterward, and results are presented and
discussed in this paper. Overall, results obtained with
both the simplified method and the FE method are in
relatively good agreement with test results.
