| 摘 要： | 在体外配筋预应力混凝土箱梁试验研究的基础上,分析其变形和裂缝的规律,比较多种现行混凝土规范变形和裂缝公式的计算结果,得出适合体外预应力配筋混凝土箱梁在正常使用极限状态下平均裂缝间距、最大裂缝宽度和跨中挠度等相关计算公式,其计算结果与试验实测值具有较好吻合性。 |
| 关 键 词： | 体外配筋 混凝土箱梁 挠度 裂缝宽度 |

| Abstract: | Based on the experimental study,the deflection and crack of externally prestressed reinforced concrete thin-walled box girder were analyzed and compared with calculated results by different formulae on deflection and crack of concrete codes.Reasonable formulae on average cracking space,cracking width and deflection of externally prestressed reinforced concrete thin-walled box girder have been proposed.The calculating results are matched with the test results well. |
| Keywords: | Externally prestressing tendon reinforced Concrete thin-walled box girder Deflection Crack width |
