文章应用梁格法,对等高腹板和不等高腹板两种截面形式的三跨、四跨曲线梁桥进行分析,以结构变形和钢材用量为主要指标比较两种截面形式的优缺点,进而给出两种截面形式的应用范围。
In this paper, the beam grid method is used to analyze the three-span and four-span curvilinear girders with two kinds of cross-sections, such as the web with the same height and the web with the unequal height. The structural deformation and the amount of the steel are taken as the main indexes to compare the advantages and disadvantages of the two cross- Given two cross-sectional forms of application.
