摘要
通过对4个钢箱-混凝土组合梁和两个空钢箱梁的抗弯承载能力试验研究,考察了钢箱-混凝土组合梁的力学性能.试验结果表明,钢箱-混凝土组合梁具有较高的承载能力、刚度以及良好的延性.用数值积分方法,考虑材料非线性,对钢箱-混凝土组合梁受力全过程的行为进行了理论分析,分析结果与试验结果基本相符.提出了梁抗弯承载能力计算公式,计算结果与试验结果吻合良好.
Four concrete-filled steel box beams and two steel box beams are tested to investigate the behavior of concrete-filled steel box beam.The results show that concrete-filled steel box beam possess high loading capacity and rigidity and good ductility.Considering the nonlinear of materials,a numerical method is applied to the analysis of the full-range loading behavior of concrete-filled steel box beam.The results of theoretic analysis agree with those of the tests basically.The calculated formula of loading capacity of concrete-filled steel box beam is proposed.The calculated results agree well with the results of the tests.
