چکیده مقاله:
Seismic performance and behavior of super-tall building is one of significant place of doubt while using energy dissipated outriggers. To improve the seismic performance of super-tall building structures using outrigger is one common method; however, the performance and behavior of the outrigger varies based on the outrigger section and more importantly the elevation and multitude of outrigger in structure, that could case great differences in seismic behavior of outrigger and the compressive force that is going to apply to mega columns. To verify the seismic performance of the building, a case study was carried out. The models was provided with two different outrigger and two different outrigger distribution and results was find out for each model to compare and present the best model that has the higher performance in whole building. The numerical models for the structures in different condition were established with the aid of ETABS software. The responses of the modeled buildings were obtained for TS 2007 and TS 2017 and compared. The results show that using outrigger at roof level could significantly affect the story displacement; however, it increases the periods at both X and Y directions.
