Abstract: A new generation of design and rehabilitation procedures that incorporate performance-based engineering concepts must be developed. These include assessing the structural strength and available capacities and contrasting them with the deformation requirements associated with acceptable performance levels. This study examines the performance of outrigger system under seismic hazards using the structural non-linear static analysis procedure (NSP). The post-yield behavior, relative damage of the structure, story shears, roof displacement, story drifts, story moments, time period, structure performance level, and response modification factor (R) of the Iconic Tower were all assessed using response spectrum analysis (RSA) and pushover analysis (POA). Moreover, this study sheds light on the structural system of The Iconic Tower for attempting to calculate the seismic response coefficient (R-Reduction Factor) also the natural frequency of the structure by the Egyptian code through an analytical study in the context of keeping up with recent developments in the field of high-rise buildings.
