Abstract EN
Considering the larger vibration amplitude and several viscoelastic material layers, a fractional-derivative Maxwell Kelvin (FDMK) viscoelastic mechanical model is proposed for “5+4” viscoelastic damping wall, which is used for vibration control of building structures.
The development of the model is based on in-parallel combination of fractional Maxwell model and fractional Kelvin model.
The proposed model is experimentally validated and very good agreement between predicted and experimental results was obtained.
The results confirm that the FDMK model is accurate in simulating the hysteresis properties of the “5+4” viscoelastic damping wall under large deformation.
From the areas of the experimental and theoretical hysteresis loops, under 300% strain, the predicted result is the most accurate in prediction of the energy dissipation and the second is the prediction under 450% strain.
Moreover, from the comparisons of dynamic properties (storage modulus, loss modulus, etc.), the FDMK model works satisfactorily.
The FDMK model is more sensitive in energy dissipation than in energy storage.
