| 摘 要： | 波形钢腹板-混凝土组合箱拱是一种新型的组合拱结构.进行了该组合拱模型的面内两点非对称加载试验.建立了考虑材料与几何双重非线性的有限元模型,对模型拱面内受力全过程进行了分析,有限元计算结果与试验结果吻合良好.研究表明,波形钢腹板-混凝土组合模型拱在弹性阶段的截面纵向应变满足"拟平截面假定",挠度计算中需考虑波形钢腹板剪切...

| Abstract: | A composite box arch with corrugated steel webs and concrete flanges is a new type of arch structures.The experiment of this new composite box arch model under asymmetrically in-plane loading is carried out.A FE model is established and its dual nonlinear behavior in the whole process is analyzed.The FE analysis result achieves good agreement with that of the experiment.Research results show that the longitudinal strain of model arch meets the assumption of Quasi-Plane-Section in the elastic stage and the e... |
