2004-6-1 The definition of the tensile behavior of concrete and, in particular, of the so-called tensile softening behavior is of paramount importance, as this last aspect controls the transition modality from the undamaged stage to the cracked one. In fact, the tensile brittle behavior of the concrete gives rise to cracking phenomena in the structure.

An instrumented impact machine was used to carry out impact tests on concrete beams, 100×125 mm in cross-section and 1400 mm long. The simply supported beams were struck at their midpoints by a 345 kg mass impact hammer, dropped from various heights. The instrumentation included strain gauges mounted on the striking end of the hammer, strain gauges mounted on one support anvil, and three ...
