Abstract In tall buildings, tubular structures have become a popular feature over the past few years. For all tall buildings, tubing in tube systems is especially tubes at the corners; the whole building behaves like a massive tube. Between the inner and outer tubes, lateral loads are exchanged. Different models were developed in the E-TABS V15 programme to research the seismic performance of tubes in tube structures by varying the position of the inner tubes. The structures are studied using a continuum method in which the horizontal slabs and beams connecting vertical components are considered to have equal distributed stiffness properties as a continuous connecting medium. To have a comparative analysis on the model, the equivalent static is evaluated Suitable. A tube contains a peripheral framed tube and a central tube interconnected by floor slabs in a tube framework. With smaller. Keywords- Tube-in-Tube, Static Analysis, Lateral Loads, E-TABS 2015
I. INTRODUCTION Advances in structural structures, increase in building height and slenderness, use of high-strength materials, decrease in building weight, etc. have now allowed lateral loads, such as wind and earthquake, to be taken into account in the design process. In design considerations, lateral forces arising from wind and seismic activities are now dominant. The lateral movement of such structures must be strictly controlled, not only for the comfort and protection of occupants, but also for the control of secondary structural effects. There are currently several structural structures that can be used to improve the lateral resistance in tall buildings, such as rigid frame, braced frame, shear-walled frame, frame-tube, braced-tube, bundled-tube and Outrigger structures. Tubular structures have been used successfully and in tall buildings are becoming a common feature. The framed tube, central tube, tube-in-tube and bundled tube are fundamental types of tubular structures. The layout of a tube-in - tube consists of a framed peripheral tube and a central tube interconnected by floor slabs. For any one of these Various simplified models have been developed for vertical components to evaluate the behaviour of the system under lateral loads. Over the past decades, several researchers have developed approximate techniques for a single tube and multi-tube device. A tube-in - tube structure’s exterior and interior columns is mounted so closely together that they not only appear to be rigid, but they also serve as a solid surface. The whole building works as a massive hollow tube with a hollow tube in the centre of it is a smaller tunnel. Between the inner and outer tubes, lateral loads are exchanged.

Tubular structures have been used successfully and in tall buildings are becoming a common feature. Basic forms of tubular systems are:– Framed Tube – Braced Tube – Bundled Tube – Tube-in-Tube The theory of the tube system is based on the idea that a building can be built by constructing it as a hollow cantilever perpendicular to the ground to withstand lateral loads. The perimeter of the outside consists of closely spaced columns in the simplest embodiment of the tube, which are connected by moment ties with deep spandrel beams. This arrangement of columns and beams forms a rigid structure along the exterior of the building that contributes to a thick and solid structural wall.
