摘要

    摘要
  • 摘要: 该文结合试验研究和理论分析对双角钢十字组合断面受力性能做了初步探索，分别考察了构件的长细比、肢宽比和填板对承载力的影响。根据薄板能量理论和虚功原理，推导出构件极限承载力公式，提出了适用于工程设计的建议计算方法，并与国内外规范计算结果进行了比较。结果表明：该理论分析模型的适用性较好，建议计算方法对工程设计有一定的适用价值。
    Abstract: The ultimate strength of a dual-angle cross combined section of high-strength steel was researched based on experimental and theoretical analyses. The influence of slenderness ratios, limb-width ratios and filled plates on the strength was researched. According to thin-plate energy theory and a virtual work principle, the formula of ultimate strength was derived and the calculation method of ultimate strength was proposed and compared with that of normal coded one. The results show that the analysis model and proposed method had theoretical and practical significance for engineering design.
