[提要] 現(xiàn)行的《碳素結(jié)構(gòu)鋼》( GB700-88)規(guī)范給出了受拉螺栓連接在偏心拉力作用下,按大、小偏心進(jìn)行計算的方法,但是并末給出大、小偏心的判別式?,F(xiàn)通過簡單的推導(dǎo)得出了一個既簡單又方便的判別式和普通螺栓群在偏心拉力作用下大、小偏心的簡單計算公式及確定中和軸位置的精確計算方法。
[關(guān)鍵詞] 偏心受拉 大小偏心 中和軸 螺栓連接 計算方法The standard Carbon Structural Steel ( GB700-88)defines the way of calculating the strength of the bolts in action of eccentric force. PJut the way doesn't tell us how to judge the eccentricity is big or small. The author has made some progress in dealing with this problem. The new discrimination and the calculating method are simple and convenient.
