摘要
以珠江黄埔大桥北汊桥钢箱梁为工程背景,根据扁平钢箱梁横隔板的受力特点,对钢箱梁横隔板进行应力分析。沿桥纵向取出2个标准梁段,分析汽车荷载轮压作用下的横隔板局部应力。分析结果可作为大跨径钢箱梁横隔板的设计依据。
With cross diaphragm diaphragm of fla cross diaphragm the steel-box grider of Huangpu Bridge over Zhujiang River as the engineering background, the stress on flat steel-box beam is analyzed according to the stressing characteristics of the cross t steel-box grider. Two standard grider segments are taken along the bridge lengthways, the partial stress acted by vehicle load wheel press is analyzed. The conclusions can be used to design gists for large-spanned cross diaphragm of flat steel-box grider
