【摘要】 总结了常规大跨斜拉桥结构计算中３个层次的计算方法、斜拉索非线性处理问题；分析桥梁常规结构计算中存在的点连接、全桥构件、局部构造、局部模型、二次效应和分步计算等问题；指出全桥结构仿真分析使用全桥空间结构模型、模型边界真实性和模型加载真实性等特征，因此其分析结果更充分、直接、精确、实用；最后通过钢板梁桥和斜拉桥的全桥仿真分析说明其特征和实用价值。更多还原

【Abstract】 A method of structural simulation for entire bridge is suggested in this paper,which overcomes some shortcomings in traditional methods of structural analysis based on pinjointed truss members and beam elements,such as inaccurate description of the connection among the members of truss and between the members and deck system,and overlooking effects on cross width of members of truss.Careful analysis of steel plate girder bridge and cablestayed bridge are given with this method.更多还原
