description abstractTwo kinds of errors are frequently encountered during the construction of cable-stayed bridges: one is force-application error in the jacking cable forces, and the other is geometry error in controlling elevations of the girders. These errors are normally kept within the prescribed tolerances by adjusting cable forces. However, the influence of creep in prestressed concrete cable-stayed bridges cannot be ignored. If this influence is not considered, it is possible to exceed the allowable stay-force range at the time when creep ends. This paper presents an optimization application in which the influence of creep can be taken into account. Some optimizing criteria are proposed, and the optimum adjusting cable forces are obtained by minimizing the amount of work due to these forces. Residual stresses due to force-application errors can also be minimized. The procedures are illustrated by several examples.
