摘要: 通过4根HRB400级钢筋混凝土简支梁的试验,观测了试件的破坏形态及变形特征,对试验结果进行了讨论和分析,研究这种结构的变形特点。试验研究结果表明,HRB400级钢筋混凝土简支梁具有足够的延性,正常使用性能较好。最后提出对这种结构的挠度公式进行修正的建议。

Abstract: The state of destroy and characteristics of deformation of the testing member are observed, the testing result is analyzed and its characteristic of deformation is studied according to the test of the HRB400 reinforced concrete simply supported beam. The testing result indicates that the HRB400 reinforced concrete simply supported beam not only has enough durability but also works well under the state of serviceability. Some suggestions on modifying the deflection formula of this type of structure are also proposed.
