1、 1 1 波形钢腹板组合梁桥课程设计 姓名： 班级： 学号： 指导老师： 2 2 摘 要 波形钢腹板组合梁桥由于具有比较优越的结构性能， 近几年来在国内国外的 运用越来越多，主要特点体现在：（1）自重小（相比与传统 PC 梁桥），有利于 减轻结构自重，抗震性能好（2）波形钢腹板主要承担剪力，不能承担纵向轴力， 纵向弯曲可不计入波形腹板的影响（3）波形钢腹板 PC 箱梁抗弯刚度、抗扭刚度 与横向刚度均比混 凝土 PC 箱梁小， 设计中应注意按适当间距设计横隔板以增大 其抗扭能力。除此之外，波形钢腹板组合箱梁特别适合于大、中跨径的多跨连续 梁桥及连续刚构桥，当跨径超过 50 米时，经济效果很明显。
2、MIDAS/Civil 是针对 土木结构，特别是分析象预应力箱型桥梁、悬索桥、斜拉桥等特殊的桥梁结构形 式，同时可以做非线性边界分析、水化热分析、材料非线性分析、静力弹塑性分 析、动力弹塑性分析，通过建模分析运算可以可以大大减轻工程计算量，提高分 析设计效率，给土木工程结构分析带来很大的方便。 关键词关键词：波形钢腹板桥梁；迈达斯；有限元分析 Abstract Corrugated steel web composite girder bridge due to structure with superior performance, more and more used in recent
3、years at home and abroad, the main characteristics embodied in: (1) the small weight, good seismic performance of corrugated steel web plate (2) the main bear shear (3) the corrugated steel web PC box girder bending stiffness and torsional stiffness and lateral stiffness are smaller than the PC gird
4、er concrete.In addition, corrugated steel web composite box girder is particularly suitable for large, medium span of multi-span continuous beam bridge and continuous rigid frame bridge, when the span of more than 50 m, the economic effect is obvious.MIDAS/Civil is for Civil structure, at the same time, can do a nonlinear boundary, hydration heat, the material nonlinear analysis, static elastoplastic analysis and dynamic elastoplastic analysis, through the analysis of the modeling alg
