ABSTRACT
Tubular structures are common structural system for tall buildings in past few years. The tubular structures are different types. The tube in tube structures are more suitable for high rise buildings. A tube in tube structure is formed by outer core (external tube) tube and inner core (internal tube) tube connected by floor slab. It is act like a huge tube with a smaller tube in middle of it. The load is transfer between these two tubes. In which a strong center tube of high strength concrete is the main load carrying structure. the load is carried by long vertical tubes at perimeter of building connected by periphery walls. This structural system improves the structural stability and increases the floor space to be utilized
