Sažetak
The results of three experimentally tested simply supported square concrete slabs with different arrangement of their equal bottom reinforcement were presented firstly. The slabs were 1.4 m × 1.4 m plane size and 50 mm depth, reinforced by rebars of 4.2 mm diameter. The first slab was reinforced by 14 rebars in both direction, the second slab by 22 rebars in x– direction and 6 rebars in y- direction, and the third slab by 28 rebars in x- direction only. Slabs were incrementally loaded up to failure by shortterm static force at slab mid-span. The previously developed numerical model of authors for non-linear analysis of concrete plates and shells [1, 2] was verified on determined experimentally results after that. The numerical model can simulates the most of dominant nonlinear effects of concrete and reinforcement, as well as the effect of structure large displacement. Using the verified numerical model of authors [1, 2], the influence of some different reinforcement arrangement of practical rectangular concrete slabs, 6 m × 6 m plane size and 0.16 m depth, on their limit strength capacity was also examined for uniformly distributed load. At the end, the main conclusion related to the optimal slab reinforcement was given.
