Analysis on Factors that Affect the Damping of Reinforced Concrete Beam under Hammering Method

Abstract:

Abstract. Damping, as one of the most important indicators of the structure’s dynamic behaviors, depicts how energy dissipates during vibration. Using Hammering Method on Reinforced Concrete Simply Supported Beam model dynamic experiment, by analyzing the vibrating signals captured during hammering process, how the allocation of the sensors and the hammer strength affect the parameter identification can be revealed. A rational method of parameter identification can be presented as well.
