Application of Composite Slab With Galvanized Steel Deck in Reinforced Concrete Frame

Composite slab which consist of galvanized steel sheet with in-situ concrete is widely used in steel framed structure due to its advantages in terms of overall weight of the structure, efficiency, practicality as it is used as a permanent form work and as positive reinforcement after the hardening of the concrete. Furthermore, it is non-propped in most of the cases. This research was aimed at investigating the possibility of using the composite slab with galvanized steel deck in reinforced concrete (RC) frames. Investigation of the efficiency and the applicability of the system included the evaluation of the composite slab with RC beam by using three different static test. Flexural capacity of the new system was investıgated through the four-point static test. These tests were used to assess the behavior of the slab which was carried by the RC beam under gravity load and the behavior was compared with the traditional concrete solid slab. Shear bond test has been done to evaluate the locally available material by m-k value method. Push-of test has been done on a series of specimens to find out the amount of slip between the beam and the slabs. As a result, it was found that the composite slab can be applied in a RC frame with a special practical consideration. Moreover, the overall weight of the RC framed structure can be reduced by using this type of slab instead of solid concrete one-way, two-way slabs, joist and flat slabs and this approach may also speed up the construction process.
