摘要
为了明确混凝土强度、钢管的径厚比、钢筋配置形式、加强肋等主要实验参数对双肢框架柱抗震性能的影响,通过对6组圆形钢管混凝土双肢框架柱在水平反复荷载作用下的试验,深入研究了圆钢管混凝土双肢框架柱的滞回性能、吸能性能和延性等抗震性能.分析了混凝土强度等主要实验参数对双肢框架柱抗震性能的影响.结果表明,钢管混凝土双肢框架柱具有良好的抗震性能,配置二重筋后会进一步增强试验体的吸能性能、承载力及延性.
In order to clarify the effect of experimental parameters,such as strength of concrete,width-thickness ratio,arrangement of reinforcing bars and ribs,on seismic resistance of CFT frame columns,experiment concerning 6 groups of circular CFT frame columns was carried out under horizontal cycling load,and hysteretic behavior,energy dissipation and ductility were studied systematically.The effect of experimental parameters such as concrete strength,diameter-thickness ratio,arrangement of reinforcing bars and steel tube with or without ribs on seismic resistance was summarized.Studies show that CFT frame column has good seismic resistance.RCFT（reinforced concrete filled steel tube） columns have excellent energy absorption performance and ductility.
