钢管混凝土肋拱面内受力全过程试验研究

EXPERIMENTAL STUDY ON MECHANIC BEHAVIORS OF CONCRETE-FILLED STEEL TUBULAR are ARCH UNDER IN PLANE LOADS

    摘要
  • 摘要: 本文进行了两根钢管混凝土单圆管肋拱面内全过程试验。试验结果表明,钢管混凝 土肋拱具有较好的弹塑性性能和较高的承载能力。本文介绍了试验的情况,分析了模型肋拱 面内受力全过程的性能,并初步探讨了其面内极限承载力的简化计算方法。

     

    Abstract: In this paper, two model experiments of the concrete-filled steel tubular (CFST) rib arch under in-plane loads are reported.It is found that CFST rib arch has good elastic-plastic behavior and high strength. The mechanic behavior Of CFST rib arch under in-plane load is studied. The simplified methods to calculate the structure's in-plane ultimate strength are discussed as well.
