六边形孔蜂窝梁和蜂窝组合梁抗剪性能分析

ANALYSIS OF SHEAR BEHAVIOR OF HEXAGON HOLE CELLULAR BEAM AND CELLULAR COMPOSITE BEAM

  • 摘要: 该文对不同参数下的正六边形孔蜂窝梁和蜂窝组合梁抗剪性能进行了试验与有限元分析研究。以试验研究为基础,基于有限元软件ABAQUS 建立非线性有限元模型,对不同开孔率、不同翼缘宽度和厚度的蜂窝梁和蜂窝组合梁进行分析比较,发现蜂窝梁和蜂窝组合梁抗剪承载力大小与翼缘厚度、开孔率和连接程度均有关。结果表明:蜂窝梁翼缘厚度变化对其抗剪承载力影响较大,而蜂窝组合梁中翼缘厚度的变化对其抗剪性能影响相对较小;混凝土板提高了蜂窝梁的抗剪极限承载能力;最后,给出蜂窝梁和蜂窝组合梁抗剪计算公式。

     

    Abstract: This article makes the research on the experimental and finite element analysis of the shear behavior of a hexagon hole cellular beam and a cellular composite beam under different parameters. Based on the experimental study, a non-linear finite element model is established on the basis of finite element software, ABAQUS. We carry out the analysis and comparison on the cellular beam and cellular composite beam of different opening rates, flange width and thickness. It was found that the shear resistance of a cellular beam and a cellular composite beam is related to their flange thickness, opening rates and connection degrees. The results show that: the flange thickness variation of a cellular beam has a greater effect on shear resistance, while the flange thickness variation of a cellular composite beam has a smaller effect on shear behavior; concrete slab improves the ultimate shear resistance of a cellular beam. Finally, we propose a calculation formula for the shearing force of a cellular beam and a cellular composite beam.
