engineering.purdue.edu• John Hancock Tower (Engineering News Record, Oct. 1975) Two dampers were added to the 60-story John Hancock Tower in Boston to reduce the response to wind gust loading. The dampers are placed at opposite ends of the fifty-eighth story, 67 m apart, and move to counteract sway as well as twisting due to the shape of the building.

ocw.mit.eduGiven a feasible solution x of LP and a feasible solution (y,s) of LD, the duality gap is simply c x− P m i=1 y ib i = (c− P m · i=1 y ia i)·x = s·x ≥ 0, because x ≥ 0 and s ≥ 0. We know from LP duality theory that so long as the pri mal problem LP is feasible and has bounded optimal objective value, then
