| 中文摘要 | 对于梁式结构,跨高比是概念设计中需要考虑的重要因素之一,目前直线型钢结构、混凝土结构以及钢-混凝土组合结构梁式的跨高比都有相关研究,对于曲线形钢-混凝土组合结构的跨高比研究尚不多见。曲线形钢-混凝土组合结构的跨高比的一个重要特点就是与曲率有关,本文结合北京南站进站立交一曲线型分联,使用通用有限元软件ANSYS对其进行分析及优化,研究了该分联的设计情况下的跨高比与曲率之间的关系。; Steel-concrete composite structure has more and more been widely used in urban bridges,for it's advantage in reducing cross-section components' size, and ascendency in improving stiffness,stability and integrity of structures and ductility of components and structures,and it's predominance in shorten the construction period as well.Among all the steel and concrete composite structure styles,the combination of steel box girder with concrete deck is now very widely used.And this style is chosen in building the cloverleaf junction of Beijing South Railway Station.The important characteristic of cross-height ratio of curve-shaped steel-concrete composite structure is that it is related to the curvature,this paper made an optimizing analysis on this subject with one curve-shaped part of Beijing south railway station cloverleaf junction as model,and analyses the relation between cross-height ratio and curvature in terms of it's design with the help of general-purpose finite element software ANSYS. |
