Abstract EN
The precise measurement of the cable force is very important for monitoring and evaluating the operation status of cable structures such as cable-stayed bridges.
The cable system should be installed with lateral dampers to reduce the vibration, which affects the precise measurement of the cable force and other cable parameters.
This paper suggests a cable model updating calculation scheme driven by the particle swarm optimization (PSO) algorithm.
By establishing a finite element model considering the static geometric nonlinearity and stress-stiffening effect firstly, an automatically finite element method model updating powered by PSO algorithm is proposed, with the aims to identify the cable force and relevant parameters of cable-damper system precisely.
Both numerical case studies and full-scale cable tests indicated that, after two rounds of updating process, the algorithm can accurately identify the cable force, moment of inertia, and damping coefficient of the cable-damper system.
