约束箱梁
1.
Based on the test results of 30 PPC restrained box girders (9 without stirrupsand 21 with stirrups), the characteristics of diagonal cracking of box girders with inflexionpoints are analyzed.
本文通过３０片部分预应力混凝土（ＰＰＣ）约束箱梁（其中９片为无箍筋，２１片为有箍筋）的抗剪试验，分析了具有反弯点的箱梁斜截面抗裂特性；指出了箱形“框架效应”、两侧腹板受力不均和宽度尺寸偏差对第一条斜裂缝的产生、开展具有的明显影响；讨论了造成约束箱梁斜裂缝开裂剪力比简支梁降低的原因；指出现行《铁路桥规》（ＴＢＪ２─８５）中斜截面抗裂性计算公式对ＰＰＣ约束箱梁、连续箱梁是不安全的；提出了考虑平均预应力度和剪跨比ｍ影响的约束箱梁斜截面开裂剪力计算公式，其试验结果与计算值吻合较好。
