This paper summarizes the results obtained form tests on a series of three-edge simply supported high-strength reinforced concerete slabs with various volume fraction of steel fiber, percentage of reinforcement and rectangularity (lengh to width ratio). The results showed that the increase in volume fraction of steel fiber and percentage of reinforcement causes an increase in the carrying capacity of these slabs, while the increase in rectangularity causes a decrease in the load carrying capacity. The increase in the yield load over the yield line theory load (membrance action) for the volume fraction of steel fibers considered (0.4%-0.8%) are 3% and 15% respectively, while the percentage increase are of the order of 16% for steel ratio 0.15%. This is in a good agreement with the results of other studies [10, 16]References
