A New Multiconstraint Method for Determining the Optimal Cable Stresses in Cable-Stayed Bridges

Table 1

Static analysis results of the simulated cable-stayed bridge.

Analysis type	Maximum bending moment at pylon bases (N·m)	Maximum top pylon deflection (m)	Maximum bending moment in main girder (N·m)	Maximum girder deflection (m)
Static analysis with pretension in cables (ULM)	7.82×10^7	0.07	7.93×10^6	0.033
Static analysis with pretension in cables (multiconstraint method)	3.35×10^7	0.009	4.81×10^6	0.017
