Abstract
本发明提供一种复合材料异形管梁结构和设计方法，其横截面包括上缘条、下缘条、左腹板、右腹板和连接缘条和腹板之间的连接部位，所述的异形管梁横截面关于过中心点的两个对称轴对称，以其1 / 4进行描述，其余三部分与之形状相同；记H为半个管梁的最大高度，H1为缘条的最大高度，B1为半个缘条的在水平面的投影长度，H2为半腹板的长度，H、H1、B1和H2满足的条件为：H1+H2≤H，0.08H<H1<0.16H；0.55H<B1<0.65H；0.7H<H2<0.9H。本发明获得更好力学性能的管梁结构，从而在大幅度减重的前提下，提高管梁结构的承弯性能、承扭性能和稳定性，从而提升结构的综合性能。
