The sensitivity of tall buildings subjected to the lateral loads is more than that of the gravity loads. Therefore, the conventional methods are not efficient yet, and new methods are proposed by designers to reduce the structural roof displacement, shear lag, overturning moment, and also increase the lateral resistance of the structures. In the design of tall structures, it is desirable to minimize the lateral stiffness of the structures for economic reasons. In this paper, the structure is modeled using the energy method and the continuous beam model. The outrigger's optimum position is calculated considering different loading patterns. It is assumed that the lateral stiffness of the structure changes with the height. An equivalent rotational spring is utilized to model the belt truss and outrigger system. The results show that the outrigger's optimum position depends on the type of the lateral load as well as how the stiffness changes in the height of the structure. |
