摘要
根据我国道路结构特点和公路荷载标准,对简支组合梁桥主梁设计的控制因素、主梁合理截面尺寸等进行分析研究。给出了公路Ⅰ级车道荷载作用下,应力控制设计时的主梁挠度,以及翼缘面积与跨径关系的近似公式,并将组合梁桥与非组合梁桥进行了对比。
In the light of the characteristics of the road structures and highway load standards in China, this paper analyzes and makes a study of the governing factors of the design and reasonable section sizes of main girders of the simply-supported highway steel and concrete composite girder bridges, gives the deflection of the girders in case the design is governed by stress under Class I Highway Traffic Load and the approximate formulas for relations between the flange areas and span length of the girders, and also compares the composite girder bridges with the non-composite ones.
