This paper presents a simple method of analysis for preliminary design of outrigger braced high‐rise shear walls subjected to horizontal loading. The shear wall has outriggers at two levels. One outrigger has a fixed location up the height of the structure, while the second can be placed at an optimum location. This position will cause a maximum reduction in lateral deflection at the top of the building. A single diagram allows for a rapid assessment of the optimum location for the second outrigger. The suggested method of analysis for use in the initial stages of the design of an outrigger structure for a proposed tall building offers a simple and rapid means of locating a second outrigger at an optimum location up the height of the structure, thereby allowing optimum dimensions for the individual structural members.
