Experimental study and seismic energy dissipation effect of composite window-type lead viscoelastic dampers
摘要
Abstract
As China's urbanization process continues to advance,increasingly stringent requirements have been imposed on the spatial efficiency and functional capabilities of building structures.To overcome the large footprint and functional interference of traditional viscoelastic dampers,a composite window-type lead viscoelastic damper(WLVED)was proposed.Installed within window openings,it integrated energy dissipation with window functionality,organically combining seismic damping and architectural function.The damper's configuration,working principle,and mechanical model were presented.Quasi-static tests on three full-scale specimens were conducted to examine the effects of loading displacement and lead core number on hysteretic behavior and energy dissipation.A finite element model was established and validated against test results,then it was used to analyze the influence of rubber and lead core parameters.Finally,the seismic performance of a 10-story concrete frame equipped with WLVEDs was evaluated.Results show that WLVEDs significantly reduce structural response under design and rare earthquakes,lowering inter-story displacement and acceleration by 39.13％and 25.00％,respectively.Compared with conventional viscous damper schemes,WLVED-equipped structures exhibit less plastic damage.By utilizing window openings with minimal impact on building function,the WLVED offers a new reference for practical engineering applications.关键词
