Experimental Study on Mechanical Properties of Small Size Viscoelastic Damper

Long span roofs are very likely to oscillate when subjected wind load that can lead structure fatigue and endanger structures safety. Dampers have been used for long time dissipate earthquake induced energy in structures. This research work aims present experimental study of small size viscoelastic damper be installed truss roof. Small dampers large roof need tested know their performance behavior mechanical properties at different loading amplitudes frequencies. A kind were manufactured under horizontal cyclic loads. Resistance deformation the measured dependence on frequency amplitude. Mechanical including shear storage modulus, loss factor dissipation studied. Experimental results show damper’s significantly related its The capacity was stable
