Abstract

A series of seven hard impact tests were carried out with 300 – 350 mm thick reinforced concrete slabs. The goal of the study was to verify the results obtained in earlier tests with 250 mm thick slabs. The results show that the effect of shear reinforcement on the punching resistance of the slabs increases when the slab thickness increases. The results also indicate that concrete parameters other than the compressive strength can affect the behaviour of the slabs considerably. More research is needed to verify and quantify the results more accurately.
