HRB500钢筋搭接焊接头抗拉性能试验研究

Abstract:通过30组90个小直径HRB500钢筋搭接焊试件的拉伸试验,研究了钢筋直径、搭接焊形式和焊缝长度对试件破坏形态、极限荷载和平均焊缝强度的影响。试验中试件共出现两种破坏形态,即焊缝断裂和钢筋拉断。试验结果表明,当发生焊缝沿受力方向断裂时,增加焊缝长度可以提高试件极限荷载,而平均焊缝强度随之降低;双面焊容易削弱焊缝端钢筋强度;焊缝偏心受力可导致焊缝一端掀起,降低焊缝承载力。对于直径6mm钢筋,最小焊缝长度可为14d(单面焊)或7d(双面焊);对于直径8mm钢筋,最小焊缝长度可为10d(单面焊)或5d(双面焊)。本文可为小直径HRB500钢筋用于焊接闭合箍筋约束高强混凝土及相关标准的制定提供参考。
