【提要】 对CFRP斜拉索的静力参数特性如切线刚度、竖向分力、垂度等进行了计算，并与传统的钢绞线斜拉索的计算结果进行了对比分析。计算结果表明：由于CFRP索的弹性模量和单位长度重量低于传统的钢索，其等效刚度系数小于钢拉索，索的竖向分力等效系数在工程应力范围内接近1，垂度效应明显小于钢拉索。
【关键词】 CFRP 斜拉索 等效刚度 竖向分力 垂度
Static Parameter Characteristic Analysis of CFRP Cables /Liu Ronggui,Li Chengji,Jiang Feng,Gong Xianghua(Department of Civil Engineering,Jiangsu University,Zhenjiang 212013,China)
Abstract:The  static parameter characters of CFRP cables such as equivalent stiffness,vertical component of forces,sag effects are computed. A series of advantages of CFRP cables are found compared  with that of steel cables. For its low elastic modulus and weight of unit length,the equivalent stiffness coefficient of CFRP cables is lower than that of steel cables. The equivalent coefficient of CFRP cables in vertical component of forces is close to 1 within engineering stress. The sag effects of CFRP cables are highly lower than that of steel cables.

Keywords:CFRP; stayedcables; equivalent stiffness; vertical component of forces; sag
