STRUCTURAL SYSTEMS USED IN VERTICAL CITIES A REVIEW

Abstract

Smart city mission in India promoted infrastructure development under various parameters like use of smart materials, smart villages, sanitation improvement, sustainable energy and many more. Introducing new vertical cities, iconic structures and use of multi-functional buildings in India is such a step ahead to achieve these parameters into reality. Vertical modern age buildings are already popular worldwide due to its advantages in terms of low consumption of area and multi-functional use. However, these buildings are subjected to intense loading due to wind, earthquake and therefore requires study to withstand safely against these complex forces and to achieve this, structural systems should be given top priority as it plays a vital role. This paper mainly focuses on the review of such structural systems which includes framed tube system, tube in tube system, bundled tube system, diagonalised-rigid system, outrigger system, shear walls, diagrid system which are usually used in high rise buildings, skyscrapers. Further study is done considering case studies of today’s top 5 skyscrapers in the world which are Kingdom tower Jeddah, Burj Khalifa Dubai, Taipei Tower Seoul, Shanghai Tower Shanghai and International Commerce Centre Hong Kong. Concluding remarks are made discussing advantages, disadvantages, comparison and suitability of these structural systems under the Indian context.
