Abstract

The relationship between natural frequency and prestress-force is built to evaluate effective prestress-force of beams based on the theory. Two corresponding test mode beams are built up to verify the theory, the experiment results show that the natural frequency will decrease along with prestress-force decreasing, which is coincident with the result of theory. As a result, effective prestress-force is predicted by using the measured natural frequencies. Therefore, the research result demonstrate it is feasible to assess the effective prestress-force with dynamical method.
