As public service life of PSC bridges is on the increase, lots of effort has been devoted to verify safety of PSC bridges. On the safety of PSC bridges, effective prestress force is one of the most important factors. At the moment, however, indirect measurements are mostly employed to evaluate the effective prestress force during and after construction. In this study, performances of FBG and EM sensors, which can directly measure the effective prestress force, are tested and investigated.
