UHPFRC panel testing

Explosive testing of full-size ultra-high performance fibre-reinforced
concrete panels was conducted in 2008. These tests and a
simplified single-degree-of-freedom analysis of the response of the
panels are reported. Each panel measured 3.5m by 1.3m by
100mm thick. The panels were contained within a large concrete
enclosure to minimise clearing around the sides from the blast
wave and placed between 7m and 12m from a 100kg TNT
equivalent explosive charge. Two of the panels were fabricated
with different levels of steel fibre dosage. The remaining two panels
were fabricated with steel fibres together with supplementary steel
bar reinforcement. Numerical computer modelling was carried out
using the ANSYS Autodyn package to predict the behaviour of the
four panels before testing. Based on the predictive modelling, each
panel was placed a suitable distance from the explosive charge so
as to cause permanent damage but not total structural collapse.
