Abstract:In the construction of concrete slabs using steel deck plates, top reinforcing bars are required at the interior supports to resist the negative moment or to restrain flexural cracking. However, such reinforcing bar work degrades constructibility and economy. In the present study, the use of steel fiber-reinforced concrete (SFRC) was studied to remove the need for on-site reinforcing bar work. To verify the effect of the steel-fiber reinforcement on crack control, flexural tests were performed for two-span composite and non-composite slabs. The major test parameters were the use of steel fiber, the types of steel deck plate, and the use of top bars. The test results showed that in the slab specimens with steel deck plates and steel fibers, the flexural stiffness and load-carrying capacities were significantly greater than those of the counterpart conventional reinforced concrete (RC) slab. Due to the high stiffness and strength of the slabs with steel deck plates and steel fibers, even without top bars, flexural cracking was successfully restrained under service loading.
