Nonlinear Static Analysison Steel Hgh-rise Buildingswith Vscoelastic Damper

GAN Jing-yan;Zhejiang Industry Polytechnic College;  
It is necessary to analyze the nonlinear static of steel high-rise buildings with viscoelastic damper because of emerging more and more high-rise buildings in our country. This paper carried it out with the finite element theory and the results showed that the stress and maxi-strain of steel frame structure located in column foot and beam end under the action of constant axial force load, the load displacement hysteric curve of the frame was the full spindle; the effect of the viscoelastic damper on the bottom position was better than that having not it and the displacement and deformation were smaller. The steel high-rise buildings with viscoelastic dampers significantly inhibited maxi shear force and displacement, it could provide a reference for the design and construction of steel high-rise buildings.
