| 摘 要： | 箱梁具有整体性好、施工方便而且受力性能好等优点,在工程界普遍采用,但目前桥梁工程中没有明确箱梁的横梁如何计算.分析高架轨道交通中常用到的中小跨径箱梁,通过建模并查看箱梁支反力以及横梁受力情况,在积累较多数据的基础上,尝试采用横梁简化计算方法去拟合结果,对中横梁和端横梁进行分析,以达到简化计算目的,并通过实例验证,供工程技术人员借鉴.

| Abstract: | Box girders are monolithic,convenient for fabrication and are commonly used in engineering at present.However,the behavior of cross beams in a box girder is not clear and up to now there is not any method available to clarify it.The paper analyzed small-and medium-span girders through FE spatial modeling and examined the reactions of box girder supports and the behavior of cross beams.Based on the data accumulated the paper postulates a simplified method to calculate cross beams including intermediate and e... |
