Abstract:

Today, design and seismic behaviour of steel structures in Turkey, especially in the design of high-rise buildings, it is very important in terms of civil engineering. On the other hand, different types of lateral load carrying steel frames are applied against horizontal effects such as especially earthquake and wind. Therefore, it is obvious that the right steel structural system selection is important. The main purpose of this study is to examine comparatively the effects of different external central steel cross types on the behaviour of these structures, which increase the resistance of steel structures, especially against earthquakes. The results obtained from the structural analyses reveal that the building models having external central steel braces are safer than the moment transmitting frame and the presence of external central steel cross members, which increase lateral rigidity in steel structures, increases the performance of the structure. This matter, the steel structures will be built in Turkey, it shows that it would be more rational to prefer steel structural systems having cross members in terms of safety.
