| 摘 要： | 本文结合拱结构计算的矩阵位移法1]和钢管混凝土拱桥分析的纤维单元法2],特提出钢管混凝土拱桥计算的实体-梁单元法。该方法便于考虑钢管初始应力和温度初应变,而且有其自身的优越性,算例计算结果表明,该方法是可行的。因此,该方法的提出为完善钢管混凝土拱桥计算理论具有重要的理论意义和参考价值。

| Abstract: | Based on matrix displacement method for arch structure and fiber element method for concrete-filled steel tube arch bridge,the solid-beam method for concrete-filled steel tube arch bridge was presented.This method is not only convenient to consider tubular initial stress and temperature initial strain,but also is of self-superiority,computing result for calculated examples indicate that this method is feasible.Therefore,this method is of great theoretical importance and is referred value. |
