Sažetak
This paper presents testing of cracked concrete slabs in a three-storey underground garage in one commercial building in Zagreb. Axial dimensions of the slabs supported by rectangular columns (1, 2 m x 0, 6 m) are 8, 0 m x 8, 0 m and their thickness is from 28 cm to 32 cm, depending on the slab's position. Most of the cracks appeared soon after construction in 2007. and since then they present a constant durability problem (corrosion of reinforcement bars and, subsequently, deterioration of concrete protection layer). Testing of the slabs was needed in order to check their load bearing capacity before making decisions about their sanation. Detailed static and dynamic tests were conducted on both cracked and undamaged slabs (in order to gain reference values).
