     outrigger-braced tall building is considered as one of the most popular and efficient tall building design because they are easier to build, save on costs and provide massive lateral stiffness. most importantly, outrigger-braced structures can strengthen a building without disturbing its aesthetic appearance and this is a significant advantage over other lateral load resisting systems. optimum location of outrigger, is an important factor to be considered while designing outrigger-braced structures. to achieve this, scientists utilize different methods including simplified methods. in this paper, optimum location of outriggers is investigated using non-linear response-history analysis. seven different ground motions are selected to consider the variation of structures responses which are subjected to seismic load cases. two different examples with zipper-braced steel cores are assessed. 20 and 30 story models are analyzed to consider the effect of height. results prove, results of simplified methods proposed by previous study are not consistent with actual response of structures and this is because of assumptions of simplified methods.
