摘　　要：冷弯试验时,钢筋表面相对弯芯放置位置不同,钢筋的变形部位将产生“位置效应”.文章用Φ18、Φ22、Φ25 3种规格的螺纹钢筋,对这种“位置效应”进行验证,得出了结论.A ＂position effect＂ usually occurs in cold bending test of ribbed steel bars, when the bending mandrel is misaligned with the bar surface. Three types of ribbed bars with diameter of 18, 22 and 25 mm respectively were tested, and the ＂position effect＂ was in fact confirmed.

关 键 词：螺纹钢筋 冷弯试验 位置效应
