The Dynamic Analysis Based On The Optimized Viscoelastic Damping Structure

This work mainly studies the application of visco-elastic dampers to seismic process of high-rise building. Finite element method (FEM) is employed to construct a model for vibration analysis of a specific high-rise building, and to present the dynamic response of the building under earthquake. In this work, the following issues are investigated.First, Energy consumption mechanism, mechanical model and solutions of dynamic equation, of the viscoelastic damper system are discussed;Second, For the aforementioned high-rise building, an optimization analysis model, considering the effect of quantity and position of damper, is established;Third, On the basis of the optimization model, the dynamic response of the buildings under vertical seismic action is analyzed.The present work provides a theoretical benchmark for various engineering appliactions...
