· Structural tube system is a tubular structural system used in tall buildings, to withstand lateral loads such as wind and seismic forces. These lateral load-resistant systems allow the building to act like a hollow cylindrical tube cantilever perpendicular to the ground. Thus the structure exhibits tubular behavior against lateral loads,

 · Abstract n this chapter, one of the widely used lateral stability system tube system is introduced. It gives detailed description on different types of tube systems, …

 · Tube in a tube (hull and core) Bundled tube Different types of structural systems Continuous structures These contain non-stop helping partitions via which the mixed hundreds and forces in a construction are transferred, particularly with the aid of using direct compression, into the subsoil via the foundations.

Tube structure Structural system for a tall building which considers the columns and spandrels on the facade as forming a pierced tube that is cantilevered from the ground.

 · Education Technology Business One of the most efficient structural systems against heavy wind loads is the bundled tube structural system The first person to …

 · There are different types of tubular structure- Framed tube structure, Tube in Tube structure, Bundled Tube structure, Braced tube Structure. These structure are basically designed to act like a hollow tube which are perpendicular to the ground. These building are basically made of Steel, concrete or composite of both.

 · A discrete tubes-in-tube structure may be modelled as an assemblage of equivalent orthotropic plate panels. Consequently, a framed-tube structure may be analysed as a continuum. Fig. 3 shows a typical framed-tube structure with multiple internal tubes (two in this case). Each of the tubes is composed of four equivalent orthotropic plate panels.

 · tube structures are formed by connecting peripheral frame tube and inner core tube. These tubes are interconnected by system of floor slabs and grid beams. As the columns of outer and inner core tubes are placed so closely, it is not seen as a solid system but it act like a solid surface.

 · The core tube maintains the critical parts of a high-rise building like lifts, ducts, stairs, etc. The external tube is the normal tube system that handles the majority of gravity and lateral loads. In this system, the internal and external tubes interact horizontally as shear and flexural branches. 4. Bundled Tube Structural System

 · II. TYPES OF TUBE STRUCTURE a. Framed Tube The organization of the framed tube system is generally one of the closely spaced exterior columns and deep spandrel beams rigidly connected together, with the entire assemblage continuous along each façade and around the building corners. The system is a logical

Tube structures are very stiff and have numerous significant advantages over other framing systems. They not only make the buildings structurally stronger and more efficient, they significantly reduce the usage of materials while simultaneously allowing buildings to reach even greater heights.

 · The tallest buildings are most often designed as tube structures. In this system stabilizing elements are located at the perimeter of the structure, leaving the layout of the interior of the building virtually unrestricted by considerations of lateral stability.
