Study on Damping of Reinforced Concrete Materials and Members
According to the spatial distribution theory of damping energy dissipation, the calculation formula of damping energy dissipation and damping ratio of a cantilever beam in one cycle are derived. It is shown that the damping characteristic of a member is affected by the material damping characteristic, stiffness distribution, mode of vibration and the sectional shape of the member, etc. The damping energy dissipation coefficient J for reinforced concrete materials is calculated by using the proposed formula considering different concrete strength, elastic modulus and reinforcement ratios based on test data available.
