摘要
本文通过对3根轴压比为0.1的钢筋混凝土箱型柱进行低周往复加载试验,探究了横向壁厚比、截面纵筋配筋率这两个因素对塑性铰长度的影响规律,得出以下结论:箱型混凝土悬臂柱在低轴压比时,其塑性铰长度是随着横向壁厚比的增大而增大的;其塑性铰长度是随着构件的纵筋配筋率的增大而增大的。
Through doing low cycle reciprocating loading test of 3 reinforced concrete box column under axial pressure ratio of 0.1,the paper explores the transverse wall thickness ratio and cross section of longitudinal reinforcement ratio on the influence law of plastic hinge length,drawing the following conclusions that the plastic hinge length of reinforced concrete box column under low axial compression ratio is increasing with the increase of the ratio of transverse wall thickness and lon-gitudinal reinforcement ratio.
