Abstract
The paper presents the results of the field tests of FRC and reinforced concrete
specimens which were performed in cooperation with the Czech Army corps in
the military training area Boletice. The tests were performed using real scale
reinforced concrete precast slabs (6×1.5×0.3 m) with varying fibre content, fibre
type, fibre strength and concrete strength class and 25 kg of TNT charges placed
at a distance from the slab for better simulation of real in-situ conditions. The
slabs were recorded using a high speed framing camera during the blast loading.
The instrumentation enabled us to study the propagation of the blast shock wave
through the material, propagation of the cracks on the soffit of the specimen and
the final collapse of the middle part of the slab exposed to blast loading. The
sequence of the structural behaviour is documented in detail and verified by
numerical modelling using the LS-DYNA solver.
Keywords: fibre reinforced concrete, high speed camera, blast loading.
