Today because of performance cobiax or slab floor structures the most recent articles with different seismic performance, conditions and methods of these structures was investigated. In this article, using the ETABS software, a Seismic evaluation and comparison of these to kind of floor structures subjected to near field earthquake presented. The results of this article demonstrated the using of slab structure in steel structure causing better seismic performance in terms of displacement.

Steel building, seismic performance, cobiax and slab floor structure, near field earthquake.
