摘要
在进行钢-混凝土组合梁设计分析时,考虑到剪力滞效应的影响,常采用翼缘有效宽度的概念计算组合结构的应力和变形。就国内外不同规范对翼缘有效宽度的规定进行了比较,指出了制订翼缘有效宽度所考虑的基本因素,阐明了我国规范和其他规范的差别,并指出我国规范的不足之处。
In the design of steel - concrete composite bridges, shear lageffects considered, the effect flange width concept is used to analyze the defections and stresses of beams Through comparison of the effect flange width provisions between several countries this paper points out, the basic factors in laying out the effective flange width provisions and the shortcomings of Chinese code.
