摘要
Abstract
Double steel plate and concrete composite walls are an efficient anti-lateral force structure,however,they are susceptible to damage under seismic loads and are difficult to repair.To address this issue,a steel edge column coupling system was introduced into the double steel plate shear wall system,resulting in the formation of the Steel Column-Double Steel Plate and Concrete Composite Wall(SC-DSPCW)system.This system utilizes steel link beams on both sides for energy dissipation,thereby reducing the extent of damage to the double steel plate shear wall structure under seismic action.Employing a performance-based design approach grounded in energy balance,nine SC-DSPCW structures were designed by varying the coupling ratio(CR)and the structural height.By simulating experiments of double steel plate connected limb shear walls and comparing the results with experimental data,the credibility of the finite element model developed using ABAQUS was verified.Through Pushover analysis and seismic time-history analysis,an in-depth investigation of the yield mechanisms and seismic performance of nine structures was conducted.The results indicate that the SC-DSPCW system,engineered with a performance-based design approach,meets the expected performance targets and displays a favorable yielding behavior.Significantly,the shear walls do not collapse,even when a majority of the steel link beams have yielded.The coupling ratio has a strong impact on the structural response;a high coupling ratio is disadvantageous as it may prevent the SC-DSPCW system from fully exhibiting its seismic resistance capabilities.关键词
