    As technology develops and world conditions change, needs and solutions in the structural field change and evolve in parallel with current methods in the field of science. Compared to alternative construction methods, steel construction systems are more robust and can provide safe structural solutions to construction needs of various geometries. In this study, structural analyses of industrial hangar-type steel structure are carried out by changing the truss arrangement and stability conditions and the obtained results are comparatively evaluated. Structural analyses of a total of 24 different industrial hangar type steel structure with the same dimensions on a fixed location are performed for 3 various truss and 6 various bracing systems under fixed and live loads, and the attained limit values are analyzed according to the practice code of structural specifications. Analysis and loading conditions are based on TS EN 1991-1-4 and TS EN 1991-1-3, TBEC (Turkey Building Earthquake Code), and RDCCPSS (Regulation on Design, Calculation and Construction Principles of Steel Structures). Seismic loads are applied to the structures within the time-history mode superposition method and dynamic analyses are performed using seismic acceleration records of the 6.8 Ms Erzincan earthquake that occurred in 1992. In the design of the steel elements, the Load and Resistance Factor Design method of RDCCPSS are taken into account. By restricting only the capacity design in the structures, at least one of each type of structural element is ensured to operate at a minimum capacity of 80% and other structural responses are obtained. The base shear force, structure weight, column top drift, apex drift and maximum displacement results obtained from the structural analyses are evaluated comparatively according to the structural analysis program. As a result, it is observed that eccentrically braced structures give more advantageous structural responses in terms of structural weight, while concentrically braced structures give more advantageous structural responses in terms of drift and displacement.
