开缝钢板墙等效交叉支撑模型
|
摘要
作为一种用于高层建筑钢结构抗侧力构件,开缝钢板墙已被验证具有良好的滞回耗能能力.在先前的1∶4缩尺开缝组合钢板墙试验中,发现开缝组合钢板墙在循环加载作用下,其极限承载力受循环应变强化的影响.通过足尺开缝组合钢板墙试验进一步验证了循环应变强化效应的存在;基于开缝钢板墙的受力性能,对普通开缝钢板墙和开缝组合钢板墙提出了统一的等效交叉支撑模型和等效支撑的恢复力模型,用于模拟开缝钢板的滞回特性.对4个普通开缝钢板墙试件和3个开缝组合钢板墙试件进行了计算机数值模拟,验证了等效交叉支撑简化模型的合理性.
A full-scale composite slit steel plate walls(CSSPW) specimen was tested,which further verified the cyclic strain hardening phenomenon.In the meanwhile,a unified model of equivalent cross brace(ECB) model and corresponding hysteretic models were proposed to simulate the hysteresis behavior of steel plate shear walls with slits and CSSPW.Numerical simulation was conducted for four specimens of steel plate shear walls and three specimens of CSSPWs,showing good accuracy of the proposed model.
