The mechanical properties of a new type of viscoelastic damper

Concrete and masonry structures crack easily. The use of dampers in cracks is a new idea on crack control. For the common viscoelastic dampers,the shear storage modulus, the loss shear modulus, the loss factor and energy consumption per week change over excitation frequency and strain amplitude. This paper introduces a new type of viscoelastic material damper. Experiments show that the shear storage modulus, loss shear modulus, loss factors of this kind of material have nothing to do with the excitation frequency and strain amplitude. Calculation and analysis of the structure will be more accurate. This damper can be used to structure crack control and vibration control.
