Multiobjective Optimal Control of Longitudinal Seismic Response of a Multitower Cable-Stayed Bridge

Table 3

Five objective functions.

Number	Description
	Controlled base shear of tower number 1 that is normalized with respect to the uncontrolled base shear of tower number 1
	Controlled base shear of tower number 2 that is normalized with respect to the uncontrolled base shear of tower number 2
	Controlled base moment of tower number 1 that is normalized with respect to the uncontrolled base moment of tower number 1
	Controlled base moment of tower number 2 that is normalized with respect to the uncontrolled base moment of tower number 2
	Controlled displacement at the left end of bridge deck that is normalized with respect to the uncontrolled displacement at the left end of bridge deck
