Abstract
Current innovative lateral load carrying systems for tall buildings are those in which the lateral drift is limited to an allowable value without considerable influence on economy. This aim is achieved by using special systems capable of using maximum stiffness and strength capacity of individual structural elements. An effective structural solution in this respect is the use of outrigger braced systems.
In the present investigation, a simple compatible structural model is proposed to analyze these systems. Constant or variable stiffness can be considered for the core which is connected to a flexible belt structure via the outrigger braced system. Several conditions including the optimum number and positions for the outrigger braced systems to minimize the drift under different loads are examined
