Tube structures are widely used system to resist lateral load of the buildings. Especially it have been applied to highrise structures. And dual core system is the system which has separated dual cores in the plan. It applies the principle to make strong geometric moment of inertia of cores in the plan by locating each cores far away. It can make rigid plan of structure and make building behave more efficiently against lateral load. It is easy to be adapted to plan of the tube structure and an improved stiffness of the plan is looked for by combining each system. In this study, tube system and dual core system are applied together and the efficiency of lateral displacement control was evaluated. And the effect of additional structural members(outrigger, belttrusse) was compared. Also the effect of an increase in quantity of core was reviewed.
