     one of the common structural systems for tall buildings is braced-tube frames. these frames provide massive lateral stiffness and enable the engineers to design structures with considerable heights. key point while deigning these structures is to obtain number of braced stories and the angle of diagrids. in this paper, optimum angle of diagrids is investigated. optimum angle will yield the minimum lateral displacement and inter-story drift. also, minimization of shear lag phenomenon is considered. cares should be taken while analyzing tall buildings. hence, non-linear response-history analysis is performed to achieve the optimum design. examples with different height are assessed to obtain the contribution of the height to the optimum design.
