Abstract :
    Steel deck ceilings are one of the most commonly used structures for building, which is used extensively today due to reduced cost. In this paper, after verifying the numerical results with the results of a laboratory sample with the help of Abakus software, and ensuring the results, 10 model plots of 3 m long and 1.2 m wide were decoupled. The thickness of the samples is chosen in such a way that the weight of the samples is equal. The parameters are concrete compressive strength, concrete slab thickness and steel plate deck thickness. Finally, the results of the numerical examples are compared with the original reference results. The results are that the steel deck ceiling has a better flexibility than the other specimens due to the lower steel plate. As can be seen, the sample of the steel deck has been displaced about 10 mm later for increasing displacement with a constant amount of force, while the concrete slab with a displacement of 1.5 mm, a 6 mm Cubax and a Uubut of about 9 mm Then they are faced with constant force. In concrete strength of 35 MPa, the standard plate deck with a thickness of 0.7 mm is about 12% more than the final load. However, in other samples, the performance of the Yubut roof is better than the steel deck, so that the thickness of the steel deck sheet has an average of 0.5-0.7 mm, only 5.6% in the load capacity of the sample.
