Abstract
In this paper, the optimum number of outriggers in a structure for minimizing top story displacement under lateral loads is investigated. To do so, the base moment and top story displacement are formulated. Then, a MATLAB code is employed to find the optimum positions of the outriggers. Different kinds of lateral loads including concentrated, uniform, triangular are taken into account. Moreover, the effects of the variation of structural elements such as column, outriggers and core on the optimal number of outriggers are examined. The results showed that the best number of outriggers depends on parameters such as axial rigidity of columns, distance of outer columns, flexural rigidity of outriggers and height of structure; by changing these parameters, the optimum number of outriggers will be changed.
