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.
