A robust finite element model updating method for pier’s structure with uncertainties in connections using particle swarm optimization algorithm

Conventional design of piers is done by assuming fully rigid connection of deck to piles. In practice, these connections are semi-rigid. Semi-rigid connections cause changes in the dynamic characteristics of the structure such as natural frequencies and mode shapes. In this study experimental modal...
