Bending Performances of High-Strength Steel-Encased Composite Beams

    摘要
  • 摘要: 为研究高强U形外包钢-混凝土组合梁在静载作用下的受弯性能，对3根完全剪力连接的混凝土强度等级为C60、C80和外包钢板强度等级为Q420、Q460的简支组合梁进行了两点对称集中加载试验.分析了试件在弹性与弹塑性阶段的受力过程、荷载-挠度关系、U形外包高强钢板与内部高强混凝土应变的分布规律、外包钢板与组合梁端部滑移、裂缝发展情况以及破坏形态等；基于试验结果，提出了高强U形外包钢-混凝土组合梁正截面受弯承载力计算方法.研究结果表明：在静载作用下，高强U形外包钢-混凝土组合梁的受弯承载力比普通外包钢组合梁提高60%以上，位移延性系数分别为2.16、2.76和2.34，说明高强U形外包钢-混凝土组合梁受弯性能良好.

     

    Abstract: In order to investigate the bending behavior of high-strength steel-encased composite beams under static load, bending performances of three simply-supported beam specimens with full-interaction and different strengths of steel and concrete were investigated experimentally. The load-defection relationship, strain distribution, steel-concrete interface slippage, crack development and failure mode of these beams were discussed. Based on the test results, the calculation formulas of normal section bearing capacity of high-strength steel-encased composite beam were presented. The research results show that compared with an ordinary composite beam, the bending capacity of a high-strength steel-encased composite beams under static load increases by over 60%, and the displacement ductility coefficients for the three beams are 2.16, 2.76 and 2.34, respectively, indicating that a high strength steel-encased composite beam has a good bending performance.
