Basic principles of global bridge monitoring, testing and analyzing system

In Finland and also in many countries many bridges have been monitored, but in the future the number of monitored bridges will be increasing. Today typically there are 20 to 100 sensors in each bridge and therefore the amount of measured data will increase a lot in the future, especially if the dynamic measurements are performed. The other main idea is that the measured data itself does not include important information for the bridge owner, because usually measurements are only series of number. Therefore the measures data should be reported and analyzed. The reporting consists of day, moth and year reports, but they can only show tends or number of incidents exceeding the defined maximum values. The paper demonstrates basic ideas, how the analyze the measured data by making analyzing or FE (Finite Element) model, by performing loading tests and by collecting all the required information into an open source platfor
