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

Table 2

Seismic control effects of the multitower cable-stayed bridge with the fully floating system.

Control objective	Uncontrolled response,	Controlled response,	Relative variation, (/
Base shear of tower number 3 (×10^3 kN)	53.518	55.824	−4.31%
Base moment of tower number 3 (×10^6 kN⋅m)	3.4155	2.4119	29.38%
Displacement on the top of tower number 3 (m)	0.6008	0.1351	77.51%
Displacement at the left end of bridge deck (m)	0.7023	0.2463	64.93%
