摘要
以某长江大桥连续组合梁桥为背景,介绍载荷步、单元生死和子模型技术在连续组合梁桥的受力特性分析中的应用。计算结果表明,该方法可以精确分析施工过程中主梁各构件的受力行为,适用于组合结构桥梁的设计及施工方案的选择。
With reference to the continuous composite box girder of a Yangtze River Bridge,this paper presents the application of load step, element birth/death and submodel techniques to the analysis of mechanical characteristics of continuous composite girder bridge. The results of calculation indicate that this method can fulfill precise analysis of the mechanical behavior of bridge members during the construction process, and it is also suitable for the design and the selection of construction scheme of composite structure bridges.
