Revival of Tubular Structures for Contemporary Super tall Buildings

Kyoung Sun Moon

ABSTRACT: 

Tubular systems developed in the 1960s opened a new era of supertall buildings with more efficient structures. Many tall buildings in the 1970s and 1980s were structured with tubular systems. Despite its inherent structural efficiency in carrying lateral loads, however, use of the tube system decreased in the following decades. In recent years,however, tubular structures in their original forms, modified forms and combined forms with other systems are widely used again for supertall buildings throughout the world. This paper reviews the resurgence of tubular structures for contemporary supertall buildings and studies their further potential.

Keywords: Tall buildings, tubular structures, framed tubes, bundled tubes, braced tubes, braced megatubes, diagrids.
