| 摘 要： | 对5根密实截面钢-混凝土组合梁的变形性能进行了试验研究。试件全部采用简支,跨中两点对称单调静力加载,考虑抗剪连接程度及栓钉布置形式的影响。得到各种情况下组合梁界面滑移分布曲线及弯矩-挠度曲线,分析其变形性能。试验结果及理论分析表明,现行钢结构规范规定的组合梁挠度计算公式对部分剪力连接组合梁来说偏于不安全,提出了相应的计算公式。

| Abstract: | Experiments of 5 simply-supported steel-concrete composite beams(SCCB) with compact steel sections are conducted to investigate the deformation behavior.The influences of degree of shear connection and stud arrangement are discussed.The changes of load-deflection relationships and the load-slip relationships along the span of beam are analyzed.Based on the experimental research and theoretical analyses,it is found that the deformations are unsafely evaluated for partial shear connection beams with the reduced stiffness method in the current Chinese code of steel structures design.The formula are derived for the rigidity of partial shear connection SCCB.The predicted of deflection values are in good with the experimental results. |
