Engineering for High Winds
The structures needed not only to support the sheer weight of the 1,360-ft-tall buildings, but to overcome the even greater loads caused by the high winds of New York Harbor pushing against the wide, flat sides of the buildings, especially along their uppermost floors. The solution: a super-strong lattice of exterior steel columns, creating a remarkably stiff "tube" that could resist high winds.
