Abstract

Abstract

Lead extrusion damper is widely used in the seismic control of structures for its large initial stiffness,high yield strength and good energy dissipation capacity.But as the lack of the research and analysis of the lead,there are more or less differences between the experiment results and the numerical simulation results of damper.A new style of lead extrusion damper was designed,called metal alloy brace(MAB).According to the result of the experiment study and using the finite element software DEFORM-3D some systemic research of this damper was done.Comparing and analyzing the experiment results and numerical simulation analysis results it concluded as follows: the MAB has an excellent energy dissipation capacity and can provide positive capacity when the structure meets larger earthquake;the size of the extrusion region,the height of the axon,the gap between axon and the cavity have significant effect on the energy dissipation capacity of the damper;during the analysis of the numerical simulation,the choice of mechanical model of lead has significant effect on the simulation result,and DEFORM-3D can be widely used in the numerical simulation analysis of metallic damper.
