摘要
通过对某双幅单箱单室波形钢腹板连续刚构桥进行有限元分析,得出该波形钢腹板连续刚构桥的自振特性,并依据承载能力等效原则,建立了相应的PC连续刚构桥有限元模型进行对比,分析了桩土效应、墩柱系梁及波形钢腹板几何形状参数等因素对桥梁自振特性的影响,得出了一些有价值的结论。
According to the finite element analysis of double-amplitude single-box and single room continuous stiff bridge,the paper concludes the self-vibration features of the corrugated steel web continuous stiff bridge,establishes respective PC continuous stiff bridge by referring to the loading capacity and undertakes the comparison of the finite element model,analyzes the influence of the bridge self-vibration features including the pile soil effect,pier column beam,and geometric shapes of the corrugated steel web,and achieves some conclusions.
