Some tests on the yield criterion for a reinforced concrete slab

This paper describes experimental work to verify the yield criterion for an isotropically reinforced concrete slab based on the concept of kinking of reinforcement bars across a fracture line. Sixteen model slabs with various arrangements of reinforcement were tested in one-way bending and experimental results have been compared with theoretical predictions. It appears that the concept of kinking is well confirmed although more tests on the behaviour of a fracture line arbitrarily inclined to the direction of the bars seem desirable.
