摘要
通过4根HRB400级钢筋混凝土两跨连续梁的试验,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,研究这种结构的塑性内力重分布特点.试验研究结果表明,HRB400级钢筋混凝土两跨连续梁能够达到完全的弯矩重分布,并且具有足够的调幅能力,能达到设计的调幅系数.提出了这种结构弯矩调幅值应将裂缝宽度作为控制条件的设计建议.
The state of destruction and characteristics of deformation of the testing member are observed , the testing result is analyzed and the characteristic of the plastic internal force redistribution is studied in this type of structure according to the test of the HRB400 continuous reinforced concrete beam. The testing result indicates that the HRB400 continuous reinforced concrete beam not only can achieve plastic internal force redistribution thoroughly and also has enough capability in the amplitude adjustment and can achieve the quotient designed.The paper advises determining quotient should take the width of crack as restraining conditions.
