摘要
对于下承式钢箱系杆拱桥来说,主梁是结构设计的关键部位。其受力性能对全桥的承载能力至关重要。因此有必要建立局部分析模型进行细部应力分析,得到主梁结构的局部应力分布特征及其传力特性,对该主梁的构造的做出综合评价。
The steel-box girder of the tie-bar arch-bridge is the key part in the structural design.Its mechanical performance is important for bearing capacity of the bridge.So it＇s necessary to carry out the detailed stress analysis.And the rationality and the reliability of the structure is appraised.
