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.

Abstract:

Through the test of four HRB4 reinforced concrete two-span continuous beams, the failure morphology and deformation characteristics of the specimens were observed, and the test results were discussed and analyzed, and the plastic internal force redistribution characteristics of this structure were studied. The experimental results show that the HRB400 reinforced concrete two-span continuous beam can achieve complete bending moment redistribution, and has sufficient amplitude modulation capacity to achieve the designed amplitude modulation coefficient. This paper proposes that the crack width should be used as the control condition for the amplitude modulation of the bending moment of this structure.
