Abstract
The paper demonstrates a numerical evaluation of strains
and deflections measured on steel suspension bridge in
Kirjalansalmi in Finland to obtain the estimation of
structure's fatigue life. The software developed in VTT
calculates also weights, speeds and positions of passing
vehicles from the measured data. The fatigue life
prediction method uses pre-calculated stress ranges
spectra in all joints from the finite element model
calibrated to the results of test loads. Since the
calculations run directly 011 the computer collecting
strain gauges and deflections measurements, the amount of
data to be transported to the central database could be
reduced significantly. The on-site computer is also
configured as web-server and the fatigue life results are
automatically updated on its web-page daily. However, the
most computationally demanding part is the stress-ranges
evaluation that iterates the whole history of strain
measurement dating back to 2011
