1、1鋼絲繩重量及最小破斷拉力計算1.1 重量重量鋼絲繩參考重量按下式計算：M = KD2式中： M -鋼絲繩單位長度的參考重量，kg/100m ;D -鋼絲繩的公稱直徑，mm;K -充分涂油的某一結(jié)構(gòu)鋼絲繩單位長度的重量系數(shù)，K值在表1給出。kg/100 mm2。1.2 破斷拉力鋼絲繩實測破斷拉力應(yīng)不低于表 24的規(guī)定。鋼絲繩最小破斷拉力用kN 表示，并按下式計算：F K'D2 R0 一 1000式中：F0 -鋼絲繩最小破斷拉力，kN;D -鋼絲繩的公稱直徑，mm;R0 -鋼絲繩公稱抗拉強度，Mpa ;K'-某一指定結(jié)構(gòu)鋼絲繩的最小拉力，系數(shù)（K'值見表1）。表1鋼絲純重
