To obtain an effective data mining method for cable-stayed bridge damage diagnosis, the algorithm of diagnosis model based on was studied, and a is proposed. This oriented to bridges. After comparison, support vector machine (SVM) limit gradient-boosting (XGBoost) algorithms, with advantages in location quantification, are combined optimized First, refined benchmark finite element established b...

The lack of computationally efficient, probabilistic performance-based design strategies for cable-stayed bridges hinders their optimal in seismic regions. Thus, this paper proposes the implementation parameterised fragility functions (PFFs) surrogate-based sensitivity analysis and optimisation these structures. In particular, PFFs are exploited to define efficient decision variables four that ...

Because the adjustment of stay cable tension and girder counterweight is limited at operation stage it a difficult problem to control negative reaction risk auxiliary pier (NRRAP) caused by multisource construction uncertainties traffic growth. This paper proposes pavement strategy optimization NRRAP adjusting thickness. The formulated as reliability-constrained, multiobjective problem, which r...
