Record High Rise, Record Low Steel

Abstract:

The Bank of China, under construction in Hong Kong, will be the world's fifth tallest building. In spite of the extraordinary codes for that city�high winds, and high live loads�the structure will use about half the steel typically required for a building of its height. The key was simplified steel connections for the cross-braced steel truss system. Members are double panels of steel stiffened and infilled with concrete. Gravity loads are gradually transferred to steel-reinforced concrete corner columns which act as shear transfer systems. This eliminates complicated three-dimensional steel connection, difficult to execute, and therefore costly. Truss members do not actually join, but sit in the column; the centroid of the truss is allowed to wander within the column within the structure. Structural engineer is Leslie Robertson; architect is I. M. Pei.
