Optimum Algorithm for the Sensor Placement on the Structure Monitoring System of Cable-Stayed Bridge

The sensor system, especially the sensor placement, plays an importance part in the research of the health monitoring system of lar ge-span cable-stayed bridge. The various optimum algorithms for the sensor pla cement at present are classified and discussed. Genetic algorithm is introduced and applied to determining the optimal position of the sensors of the monitorin g system of th e single-tower cable-stayed bridge of the Zhaobaoshan in Ningbo. Numerical sim ulation results indicates that this algorithm has a good convergence and abilit y to get the stable and reliable solution.
