Mechanics analysis and experimental study on energy dissipation damper based on bending and dislocating

This paper introduces an energy dissipation damper laminating steel plates and rubber based on the project of Hejing Tower in Guangzhou and used for vibration control on the glass curtain wall. The theoretical analysis of the viscoelastic damper which dissipates energy by bending and dislocating are studied, and the interface between the damper design and the software calculation with ANSYS is set up. The Kelvin-Voigt modal for damping is used and the equivalent damping force is found in the dampers analysis according to geometrical relationships and physical relationships which is checked and analyzed under the same working conditional dynamic experiments. All the energy-dissipation dampers of any size and layout can be simulated for the damping element which is applied to the software of ANSYS, which in turn can be applied to do time-history analysis of vibration control on the whole structure with this theory. It is shown that the results of the theoretical calculation, the dynamic experiment under the same working condition of the project of Hejing Tower and the ANSYS calculation agree with one another fairly well. It is also demonstrated that the theory in this paper can be commonly used in the engineering design of the energy dissipation damper.
