The joined-wing configuration, as compared with the normal configuration, is characterized by low structuralweight, small induced drag, big lift coefficient and good stability.
联结翼布局与常规布局相比具有结构重量轻、诱导阻力小、升力系数大和稳定性良好的特点。

To reduce the overall weight of the building, it used less concrete in the floors; that in turn enabled it to cut down on structural steel.
为了减少建筑的整体重量，它在楼层中使用了较少的混凝土；这反过来又减少了对结构钢的使用。
