摘要:
针对一般研究桥梁传递关系都是以初参数法为基础，公式较为繁琐且占用内存空间大这一问题，利用辅助体系法对空间直线梁桥的受力特性进行了分析.为了更好的研究空间直线梁桥的传递关系，为大型桥梁的设计与结构分析提供可靠的依据，基于辅助体系法并考虑了剪切变形导出了空间直梁的场传递矩阵精确解, 并推导了不同支承情况的点传递矩阵．编制了相应的计算机程序，并进行了算例计算.算例结果表明，该方法正确有效，可用于结构的初步设计和最终校核．
Abstract:
In view of the fact that the vast majority of the research work is performed based on original parameter method and the calculating expressions arecomplicated and needed too much memory space, the mechanical characteristic of the space bridge was analyzed by using auxiliary system method. In order to research the transfer relationship of the space straight bridge well, according to the auxiliary system method, the field transfer matrix and the point transfer matrix with different support conditions of the space straight bridge was derived and the load items with different loads were calculated for the bridge design and structural analysis. In addition, the corresponding caculation program was compiled, and some example were carried out. The results indicate that the method is correct and efficient, and can be used for the initial design and final check-up of structures.
