1、钢丝绳验算过程结构吊装中常用钢丝绳是先由若干根钢丝捻成股，再由若干股围绕绳芯捻 成绳，其规格6X19、6X37和6X61等种（6股，每股分别由19、37、61根 钢丝捻成）。前者钢丝粗，较硬，不易弯曲，多用作缆风绳。后者钢丝细，较 柔软，多用作起重吊索。钢丝绳参数如下表所示。表0-1 6X37钢丝绳参数表钢丝绳 公称直径钢丝绳参考重量/钢丝绳公称抗拉强度/Mpa15701670177018701960(kg/100m)钢丝绳最小破断拉力/kN天合然成钢纤钢纤钢纤钢纤钢纤钢允许纤纤芯维芯维芯维芯维芯维芯D/m偏差维维钢芯钢芯钢芯钢芯钢芯钢m/芯芯丝钢丝钢丝钢丝钢丝钢丝%钢钢绳丝绳丝绳丝绳丝绳丝绳
