<p>In the current investigation, for a 60-story building with a 180-m height, a dynamic analysis of the outrigger system was performed. The study results are designed to compare the performance of single outriggers vs. multi-outriggers and to analyze the performance of different outrigger configurations, which include X, V, inverted V, and shear walls. According to Taranath’s theory, the outriggers were placed at (1/n + 1), (2/n + 1), (3/n + 1), (4/n + 1), and (n/n + 1) heights. The structural model with a shear wall core was examined together with various outrigger layouts in ETABS. The results obtained were in terms of some vital parameters like maximum story displacement, story drift and story shear. The dynamic response spectrum analysis of earthquake loads and the static analysis of wind loads were carried out. In addition to these analyses the dynamic wind analysis was also carried out, which is particularly more critical for taller structures. The results showed that increasing the number of outriggers increased the lateral load capacity of the structure. The inverted V-type steel outrigger had the best effect in the practical application. In fact, for the current examples, it was observed that a shear wall used as an outrigger works better than steel outriggers. Furthermore, belt trusses or shear bands were also introduced to improve the performance of the outrigger system. Additionally, the optimal number of outriggers is identified by evaluating the incremental improvement for each outrigger addition, which shows that after the third outrigger, the performance improvement becomes insignificant, suggesting 3 outriggers as the optimum number.</p>
