| 摘 要： | 以近期中标的两座桥梁为背景，依照BS5400进行设计，用MIDAS有限元软件分析结构受力特性，然后用先简支后连续结构的作用效应结果与纯简支梁及纯连续梁的情况作比较，得出结论，以便后续同类型桥梁设计者进行参考。

| Abstract: | Considering the condition and restriction of bridge construction in Nigeria, our company introduced simply sup-ported-continuous system for the two new bade bridges, and got the design target of economy, security and beauty, after comparing different plans and thinking comprehensively. This essay is based on the design of the two bridges, abiding by the code of BS5400,applying the finite element analysis software of MIDAS to get the structure reaction, and then compares the results of simply supported-continuous system and those of the simple supported beam or continuous beam, and gets the conclusion, which may provide reference for following similar designs. |
