|Abstract: ||The socio-economic situations in large cities of Ethiopia are creating a strong need to the construction of tall buildings. To satisfy this need an economical and efficient design of high- rise buildings should be adopted. As it is well known, the structural system plays a great role in the design of high- rise buildings.
Framed-tube and tube in tube structural systems are systems, which have received wide acceptance among designers all over the world for tall buildings.
In this research work a comprehensive literature survey on historical background and design criteria of high-rise buildings and their structural system is conducted. The literature survey covers also tubular structures and their behaviour, approximate methods of analysing and design of framed tube buildings.
After the literature survey, analysis of sample framed tube, shear-wall frame and tube in tube buildings is carried out, in order to compare the effectiveness of the structural systems. Then, analysis results are evaluated, based on the design criteria p-delta effect, drift and stiffness degradation. Comparative analysis between framed tube and frame-shear wall buildings based on their concrete requirement is also made.
Finally, conclusions and recommendations are forwarded for the use of framed-tube and tube-in tube structural systems for tall buildings. Essentially, architects have to familiarise themselves with these structural systems, as they have influence on the architectural expressions of the building.|
