STUDY ON Nu -Mu CORRELATION CURVES OF CONCRETE FILLED DOUBLE SKIN STEEL TUBULAR (CFDST) BEAM-COLUMNS WITH EXTERNAL STAINLESS STEEL TUBE

  • 摘要: 外包不锈钢管中空夹层钢管混凝土构件结合了中空夹层钢管混凝土(CFDST)与不锈钢的优点,在桥墩、海洋平台与输电塔结构中有广泛应用前景。为此,该文基于前期试验,采用自编纤维模型法程序对225个外包不锈钢管CFDST压弯构件进行了系统分析。研究了各参数对该类压弯构件典型N/Nu-M/Mu曲线的影响,并将相关曲线与普通外包碳素钢管CFDST构件进行了对比,最后提出了该类压弯构件N/Nu-M/Mu相关曲线方程。分析结果表明:该文自编纤维模型法程序可较好预测外包不锈钢管CFDST构件压弯承载力以及N/Nu-M/Mu曲线的发展;混凝土强度、内管径厚比、钢材屈服强度、空心率、名义含钢率与长细比影响N/Nu-M/Mu曲线的形状;由于不锈钢材料明显的应变强化效应,相比于外包碳素钢管CFDST构件,外包不锈钢管CFDST构件的N/Nu-M/Mu曲线接近于钢结构;基于试验与参数分析结果以及外包碳素钢CFDST计算公式,得到了外包不锈钢CFDST相关曲线特征点公式和曲线方程,与程序计算结果吻合较好。
