The scope of the current thesis is the investigation of the seismic behavior of complex structures of soccer stadium in the city of Adana, Turkey. The main structural parts of the building of the stadium are reinforced concrete tribunes, steel façade and cable-stayed roof, resting on the structures of the façade. The behavior of the coupled model in case of seismic excitation is studied. The coupled model is defined as a structural model that contains together all main structural parts: the tribunes, the façade and the roof. In the engineering practice, a large-span roof and supporting substructures (façade, tribunes) are differentiated and analyzed separately. In case when the seismic analysis has to be done, the separated analysis has to be performed with caution and possible amplification effect of the seismic action for the structural model with all main structural blocks introduced has to be taken into account. The amplification effect is defined as the increase of the displacements, total base shear and internal forces in the structural elements. To investigate the extent of the amplification effect, the results obtained from the analysis of coupled and uncoupled models were compared. The results obtained from the modal spectral response analysis and nonlinear dynamic analysis of different structural models show a significant amplification of the displacements of the roof structure and façade bearing columns for a coupled model, with the subsequent increase of the total base shear transferred to the substructures form the roof and internal forces in the elements. Methods of improving the structural behavior for the seismic excitation have been investigated. In particular, the effect of installation of seismic isolators for the roof structures has been studied. For the structural models with the isolated roof, the results of the analysis of both coupled and uncoupled models have been improved and all design requirements have been verified.
